Since you have taken the membership only two weeks back and also intimated that you took the membership under pressure from the representative, the agreement can be revoked and you would be entitled to a complete refund, if the payment has already been released then you have to issue a legal notice and then proceed to file the complaint before the District consumer forum, at Bangalore.
I have filed similar cases against Country club vacations and the matter is almost reaching finality. You may contact me if you wish to pursue the complaint.
