Kotak Mahindra Bank — approved transaction for exceeded credit limit.

Address:

Hi, this is fraudulent transaction that went through on 17feb 2020 for the bill of 10998/-. I am completely responsible for the fraudulent transaction as i must have been carefull. Yet, the amount exceeded by the credit limit. It was over due by 4000/-.
So my dispute is that why was the transaction even approved when their was not sufficient credit limit.
