That all banks in Qatar are less than world class standards, all have screwed up something for someone, and the important thing is to get someone to help you solve the problems when they arise and they will.

I have a branch manager who has been great at fixing a couple of screw-ups at QNB. Find a branch of one of the banks that will be convenient to where you live or work (Parking and traffic can be a killer), talk to the manager or someone and explain you will need help being new, etc and how can you get in touch when you need the help. Get a live body to talk to when you need it. If they don't want your business enough to give you a contact, find another branch or bank. When you find it, do most of your banking at that branch, talk to your contact, visit and make friends. They help the people they know.

You will have problems, how they handle them is the key. Don't do problems over the phone if you can help it, see someone.
