I reached out to global doors for help as after five years after the door I purchased from them started to drop and was not locking properly.

This is their response:

As the hinges on the door are a butt/fixed hinge there isn't an adjustment through the hinges that can be made. Other than making sure that all the screws in the hinges have been tightened and similarly in the frame fixings, you may be best speaking to an experienced door fitter to see if they have tried and tested methods.

Basically, “computer says no” so great looking doors, but the doors cannot be realised because they are not using adjustable hinges.

I reached that again to see why they were unwilling to help. I have not had a response.
