Standard Chartered Bank Credit Card — Incorrect Statement no reply from bank

Address:

Pune, Maharashtra

A statement was sent on 15th Jul 2013 of 4027 Rs for which I made payment on 18th Jul 2013, Due date of the statement was 5th Aug 2013. Now I received a statement on 15th Aug 2013, which says previous dues not paid, plus late fees plus interest accrued plus current dues. I emailed, lodged a complaint, tried to connect through phone, but no response I got. This had happened second time. They replied that they won''t be able to revert the charges for the first time. This time no response. Worst customer care service.
