One Assist Mfee — deactivation the one assist mfee and refund my amount of rs. 2199

Dear sir/madam,
I am s. Kannan (Mobile - [protected]), hdfc credit card holder, from chennai. I don't have any interest about one assist mfee membership. But the amount of rs 2199 debited from my cred card account for one assist mfee. So please deactivate that membership and refund my amount as soon as possible.
Thank you
