CBQ is rip off.
Highest interest rate than any other bank in Qatar. So much of hidden charges. Charge you even for asking questions (lol). Their credit card is nightmare.

Just go any of their branch in rush hour. meet one of the customer service agent, create some scene. they will solve it. make sure you cancel the card (at any cost) as soon as they close the case. Good luck.

I personally know about 10+ people who cancelled CBQ and went to other banks.
