One Assist Membership — Cancellation of my one assist membership

Cancellation of One Assist Membership
I am a HDFC bank credit card holder . The bank has auto debited Rs. 1899/- from my credit card number ending with 7288 without my concern on date:14/10/2020. 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.1899/-
