I have done a biggest mistake by getting HSBC credit card. From last two months I am getting daily 2-3 calls regarding BALANCE TRANSFER FACILITY from their end. I have told many times to them that i am not interested, still they are calling me everyday. Even i requested them to put a remarks their with my no. that I don't want to get any call from they, though they are sincerely giving me calls everyday without fail.

Can anybody tell me how to deal with this ??
