Michael Kors (Sold for P1800, big liar buyer re-selling for 5500) Philippines

I sold several items to a buyer who pleaded and begged that she will use the the item personally, and that its her first time to own expensive stuff. SHE EVEN TOLD ME THAT SHE WILL NOT RE-SELL THE ITEMS (since I hate re-sellers and she knows that). And so I gave in to her stories. I gave her my stuff below the market price, hoping that I made one Mom happy! Now I just found out that all the stories were lies! She is now re-selling these items in her newly created Sulit account, at double the price! Beware! You will know who she is. Just search for the same item.  I can't take the way she lives her life -- full of manipulation & lies, just for some money!
