[Resolved]  Tata - SBI Credit Card — Kept on increasing outstanding balance

I had a credit card of TATA-SBI in 2008-09. In one of their last statement of 12.02.2008, they included a finance charges of 534.01 INR. When i called up customer care, they told me to pay the amount, but never told me the reason of the inclusion. With many follow up calls to the customer care and paying no heed by them towards my complaint, I paid off the amount excluding the finance charges levied by them and then asked them to close the account. For nearly 5 years, i never got a call back from them, but suddenly on 18-Jan 2014, I got a call from SBI cards asking me to pay off my outstanding amount of approx. 13, 000 INR !!! When i asked details, the person couldn't furnish details and gave me warning of consequences if I do not pay the said amount. I again called up the customer care, where they confirmed the amount but when i asked details they told me that they do not have any details as the account is very old. I even wrote to Nodal officer but for no use. No one is really listening in SBI credit card section and I am really tired of following up from my side, calling customer care and writing mails to nodal officer. Please help me to close my account with a rational discussion on the issue.
