When I think of Wintech, I think of my hurtful days dealing with Zap Infotech, a subsidary of Wintech. The company has nothing but money and know very well how to play with money! They spend their money on pull-page ads in times computing when they should be spending it on improving the current members they have already. They act like they are pros but they really are chours. I had an appointment set with their head, Abbas Mithani, and guess what... when we reached their at dot 4:00 PM IST, Mr. Mithanis secretary says that he is in the meeting. I am sorry Mr. Mithani but you have just broken the number one business rule: not fulfulling the needs of your customers. I walked away and never got my money back until this day!
I say not to join the classes even if they pay you because today time is money! And if you rather spend your time somewhere else, you will learn more than you would at a branch of Wintech.
Still if you have doubts, leave a comment and I will give you more and more reasons you should not join them(bcuz I cant type my whole story here!).
