I got SBI Gold and more Credit card around
one year ago. with this credit card, I also got 2 supplement credit
cards for my family. I want to cancel all three credit cards. I tried
to cancel these card by phone or by post but customer care executive
refused to cancel these cards stating that my Date of birth is not
correct and even i emailed to them but the didn't replyed. While applying for credit cards, agent told me that these
cards are free and i don't have to pay any annual fee. But they are
deducting 26.97rs every month from June 2012. I want all my money
refunded and want to cancel all these credit cards immediately. My
