In 2004 i was issued a credit card by some of your officials which i never used. I don’t have that either probably some annual charges accumulated.
I am continually trying to pay off its balance which is 5405 rupees (As informed by state bank) but none of your bank branch is owning that there is anything payable
Whereas state bank is showing my credit history as write off
Either you tell me where to pay this amount? Or i will go to the court
