Lalit — Unauthorized auto deduction of amount

I am a hdfc credit card holder. On 30th july, 2020. I received
a message from hdfc bank (one assist mfee) in which they had deducted
(₹1899) from my account against my will.
I am not interested in this membership and also wanted to cancel this membership .
I want my money back. If you are not giving this I will file a case against you in the district consumer court.

Name- Lalit
