HDFC Bank — Deactivation of one assist

Hi,
Am having hdfc credit card and am not using the card for the past two years. Last year i raised a query to deactivate the one assist service for this but they auto debited the amount from my hdfc savings account.
Now also they send the credit card statement for auto debiting.
Please cancel this service.
