HDFC Bank — Deactivation of one assist membership

Address: Gr Flr, Kh No 832, Pargana Barhar Ghorawal Sonbhadra-231210

I am a hdfc bank credit card holder. The bank has auto debited rs. 1299/- from my credit card number ending with 6764 without my concern on date:12/05/2020. 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. 1309/-
