[Resolved]  SBI - Credit Card — SBI credit card - never responses and creates problem for other- From Credit Burreau should give me the clearance as this is the fault of SBI

I was using one SBI credit card 3.5 years back when i was at Indore . Later i shifted to Ahmedabad . Called for address change but never happened and also i never got any statement . Once i called up at Customer care to close the account and with some lady i talked and as per her instruction i teared the card .
But now after 3 year i came to know that i have a due of 18 k., called up customer care and to clear the dispute i agreed to pay Rs. 8660.00 for settlement, even provided them the cheque number. Called atleast 6-7 times from last one month, sent mail but till date not solved my problems . Because of the same my project got stucked .
SBI service is wrost ever service i have ever seen .
