Kotak Mahindra Bank — credit card complaint

Kotak executive called me for credit card and assured credit of 70k. He issued credit card of 30k credit limit after 15 days. I called the executive and cancelled my card. He said the credit card is cancelled from bank. But after one week, without informing he activated one asst service which was charged 1299/-. Now for cancellation they are telling it will take 15 days and if statement is generated i will be charged 1299/- also i have called to cancel card it is still not done. This is how i have been fooled and bank is activating new way of cheating their customers. It want my one asst services to get deactivated instantly and credit card to be cancelled.
