BARCLAYS CREDIT CARDS
Incorrect charges

Hi,

I had a Barclays creadit card. Some 4 months back, I dropped the check for payment in the drop box 4 days before the due date. But the bank cleared the check after the due date and charged me 'late fees'.

That was very bad service. And after that, I cancelled the card. But still they are troubling me with sms and phone calls for payment of the late fees. I explained them how bad their service was, but still they are not understanding. Can anyone tell me how to complain about this to RBI?

thanks

Nayana
