HDFC Bank — Unauthorized plan against my credit card

I'm using HDFC CREDIT CARD SINCE LAST 2 YEAR CARD NUMBER ENDING with 7**7My account is activated with ONE ASSIST MFEE and charged Amount 1399 Rs just now with out my knowledge. I want to cancel the unauthorized plan against my Card, and also credit my money in my credit card which you have deducted in my credit card account.

Also this is unfair that you cannot deduct the amount from the credit card without prior notice through call/message.
And HDFC Bank also has to recheck this issue with the Auto Payment modes.

This is the 2nd year I'm requesting again for the cancellation of this ONE ASSIST plan. Please kindly take a notice and CANCEL the plan and repay my amount Rs.1399 as soon as possible.

So request you to please cancel this activation against my credit card, and refund my money also. Plz arrange a call for me...
