[Resolved]  HDFC Bank — transaction not done my me/ expired card being billed.

This is regarding the credit card of hdfc i have been using.
The card has been expired long back but the credit card department keeps charging the interest and other fees without issuing a new card.
The complaint via phone number does not work at all and also the web link does not work.
The request for a new card was simply dismissed saying the signature was not correct.
Am trying to close the account at one shot but the bank keeps additional fees.
Need justice or a fair deal to close the issue.
Kindly help.
