HDFC Bank — hdfc credit card

Hi,
I am a hdfc bank credit card holder. The bank has auto debited rs. 1299/- from my credit card number ending with 5625 without my concern on date:20/10/2017. I am not interested about this service and don't want this membership any more. So cancel the membership and refund this debited amount of rs.1299/-
