Hello, thanks for your inquiry. The learning curve of each person varies. Therefore, any given person could learn Sir Renie's system in 5 hours, after a day, a few days, or a few weeks. It really depends.
What I can only guarantee is that he is an expert. He has trained would-be call center agents. Other training programs cost from Php 2,000 up to PhP 5,000 yet they are not as effective as his system.
Landmark would be the Tektite Towers. It is directly in front of Tektite. Say you are commuting and you arrived at Edsa Shangrila. Go to the Jeepney Terminal, and ride the jeep going to UGONG. It will pass by TEKTITE.
