Case details:

Aug. 29 - 12:49pm: 1st text from the "scammer"

Scammer (09476339138) texted me expressing intention to purchase one of the items I'm selling (Media Player). My selling price is Php 3,980, but the seller wants to get it for Php 3,500.

I asked what his name is and he mentioned he is "James A." (surname withheld for confidentiality) and he saw the ad from Sulit. (I failed to asked if he had an actual account name in Sulit though).  

[note from hindsight: the scammer used the name of a prospective buyer whose real name is "James A".   This prospective buyer becomes the victim of the scammer. Unfortunately, the "scammer" told the victim "James A." that he is me, so my name is at stake.]

I told him that Php 3,980 is already the best price. He said that he will make a deposit to my BDO bank account for Php 3,500. And that he will borrow the remaining balance of Php 480 to pay when he asks his Tito to pick up the item. I said OK, you can make deposit to signify that he is reserving the item and he will be picking up the item soon, with the balance to be paid during pickup.

I gave him my BDO bank account details, and he mentioned he will make the deposit tomorrow.

At around 5-6pm, he texted again saying he will try to deposit the Php 3.5k to BDO (which is still open inside SM malls). But later, he texted na hindi na siya umabot, so he will make the deposit the next day.

Aug. 30 - 9:29am:  "Scammer" texted me that he had already made a deposit of Php 3.5k to my BDO bank account

I contacted the bank to check if a payment has been deposited to my account -- and the bank confirmed the said payment (cash deposit).

[note from hindsight: the real "James A" deposited Php 3.5k to my bank account, not the "scammer". The "scammer" asked me to check that it has been deposited to my account. Note that the "scammer" relayed the bank info I give him to the victim "James A."]

"Scammer" then texted me that he will ask his "Tito" to go to my office to pick up the item. So I gave him our exact location to pickup the said item (Media Player). He also gave his Tito's number (09993419818) and his Tito's name, which is "James D." (ibang apelyido) and also what he is wearing. Tito texted me that he is about to arrive at my place to pick up the item.

A few moments before the Tito arrived at my place, "Scammer" called me up to say that he just looked at the detailed specs of the Media Player, and found out that it may not be compatible with his receiver (for connecting the Media Player). Scammer asked if I can refund the payment since he has changed his decision and will not buy the item. He told me to deduct Php 200 from the deposit he made and then give the refund (Php 3,300) to his Tito.

Around 1pm, his Tito arrives at my place, and told the same story -- his nephew has changed his mind about getting the Media Player, and asks for the refund, less Php 200 for the hassle they caused.   I accepted this and gave the "scammer's Tito" Php 3,300.  

[in hindsight: I should have made a written refund slip for the Php 3,300 indicating that the Tito has received the refund.

now that I think about it, the person "Tito" who came to my place could very well be the scammer -- he probably just used 2 different cellphone numbers to show that they are 2 different persons.]

Oh well, I thought this was just a cancelled transaction..

Fast forward to today,

Sept. 3, 5pm: The bank officer of BDO where I have an account called me up and relayed about a complaint they received with regards to my account.

She said that a certain "James A" called them up, insisting he made a payment deposit of Php 3,500 to my account last weekend, and he is complaining that I did not ship the item which he paid.

I asked the bank officer what item "James A" mentioned he bought from me, the bank officer said that it was an external hard drive. I told the bank officer that "James A" did not buy an external hard drive, but was interested in purchasing a Media Player, who

This (real) "James A" told the bank that my contact number is 09476339138 daw. The bank officer said that this (real) James A. was contacting "me" (at the 094763398138 number) and could not reach me. Which is why he called up the bank, and the bank officer is now relaying this info to me.

(note: My contact number is clearly posted in my Sulit account, so if this real James A was really buying from me, he would know my contact numbers.)

I told the bank officer that the one who deposited Php 3.5k is a certain James A (who is the real James A., not the scammer who used that name), and I mentioned it was from 09476339138 who mentioned depositing the payment.

So, the real James A. told them he deposited payment to my account, and my contact # is 09476339138. The bank officer also told me that (the real) James A gave them their contact # which is 0917xxxxxxxx (I told her that the "James A" that I had in contact with had the number 09476339138, so that does not make sense.).

I told the bank that true, James A. did deposit to my account for Php 3.5k, and "James A" (the scammer)'s contact # is 09476339138.

But it was not an external hard drive, but a media player, and I have already refunded the payment since it was cancelled.

The above are the case details. I still have almost all the text messages from 09476339138 saved on my cellphone for reference, if needed. (fortunately, I had not deleted those messages yet).

Now, the scammer (cellphone # 09476339138) could not be contacted anymore ("unattended or out of coverage area"), since he made off with the Php 3,300 that I refunded (bank deposit payment from the "real James A.").

In summary:

I have not transacted with the real James A., but I had a cancelled (scammed) transaction with the scammer who told me his name is "James A" (including his Tito, which could have been one and the same person).

However, it's true that the real James A. had made a deposit to my bank account (since the scammer 09476339138 gave him my bank account details). And also since the scammer decided to cancel buying the item, I had refunded the said amount (less Php 200) to the scammer/Tito.

The victim is the real James A, who had paid Php 3.5k.

For now, I haven't any monetary loss yet, since the amount that was deposited to my account, I had refunded (less Php200) to the scammer. BUT MY NAME is at STAKE, since the scammer told the real James A, that he is ME. (so that MY NAME is now the SCAMMER). And it's true that my bank account was used in this case.

But the things that didn't jibe are: where did this real James A find out about the Scammer's products? (If this real James A had seen my items/ads in Sulit, he would have known my contact #.)  And also the scammer had been communicating with the real James A. using his cellphone number 09476339138, but impersonating as ME (and using my bank account for the payment deposit).

I haven't contacted the real James A (the bank officer gave me his number) yet to explain my side (I had not transacted with him in the first place, it was the scammer who used my name to transact with him). What should I do?

Paano po ito??? Please advice!
