Un authorized debit to my account

On the 13th of April, I received a message stating that an amount of Rs. 1350 has been debited to my Andhra Bank Credit Card, which came as a shocker to me, since I have not authorized the above company for any such transaction.  Neither I have availed any services from them, even if it was done so, they can not debit to my account every month.  I do not want any services from the company above and they must return my payment back to my account, without any further delay. and stop doing this kind of activities.
