What should I do now?

If that's the case, speak to someone at B&Q about a possible warranty claim, they will probably want to send someone out to look at the doors, who will then tell you if they are at fault or the fitter, which way does the guy reckon they are bowed? try putting a straight edge against the doors to see if any of the sections have a slight curve

I have put a spirit level on the door and it is bowed slightly, Vertically inwards looking at it from the outside if you see what i mean.
