I've got an integrated Belling MultiFunction Cooker. Since I moved into my house, the door on that cooker won't close properly.

I've dismantled it a few times now and all I can find wrong is that a screw on one of the hinges won't tighten (although that may be due to my own actions).

Anybody know anything else I can try? Alternatively, is there a customer support number I can ring in Ireland?
