HDFC Bank — Credit card payment not credited

Address:

New Delhi, Delhi, 110002

On 31st December, 2015 I made a payment of Rs. 3200 against my old credit card number ending with 7089. This card account has been closed. When I called the customer care, they responded that my money would be credited to my new credit card number ending with 2334 withing 48 hours. It has been 15 days and the money is yet to be credited to my new credit card account. My repeated attempt to mail to HDFC through netbanking mail service has resulted in vain. I am feeling helpless at the pathetic dont-care attitude of the bank representatives.
