HDFC Bank — hdfc credit card cancellation of 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 without my concern on date: 20/11/2019. I am not interested about this service and don't want this membership any more. I have informed the same last year to oneassist. So cancel this membership and refund the debited amount of rs.1899/-

Note that last time oneassist customer service keep on trying to convince me instead of cancelling the membership.
