From last 8 months I am holding a card of Barclays Bank with card No.[protected] In month of January 2008, I have made my last purchase, against which total outstanding balance of Rs.1761/- was there against which I have made the complete payment through cheque which was being cleared ( enclosed the statement. After that when I received the next statement there were certain charges added, when I called up at the customer care they said these are just the finance charges I am taking a request the reverse them, you don’t pay them after that again, in the next statement few charges were added along with late payment fee of the previous charges. I again called up at the customer care but no response was there. Now after my continuous requests. i finally send at request to grevience call of barclays card.
