[Resolved]  HDFC Bank — need to close credit card

I have paid off the balance few yrs back but they keep sending me bill & not closing the card. Last year i went to bank & sent the broken card along with closure form with the help of their bank executive in chhatarpur branch, new delhi -74. But card is stil not closed. Their service is pathetic & they do that intentionally. If the balance is paid off they should have the option to close over the phone like other banks do. I blocked my card also but they generated new card which they never sent to me.
