SBI Credit Card - Cheating money in the name of personal loans

Sir/Madam,
I am a Medical practitioner working in one of the biggest hospitals in Chennai.I am very painful to say that people of SBI credit card,approached me several times before luring me in SBI credit card.Without knowing how Fraudulent it is I bought the card in January 2007 only to realise how they fooled few months later.They kept adding interest rates at higly un-acceptable levels and confused me by the system of reapayment.
Ultimately I grew very impatient that I closed the SBI card in October 2007,but I cleared the high interest.
I request you to kindly arrange for BANNING SBI CREDIT CARD.
Thanking you,
Yours truly
