Front Door adjustment help

[Sneezin]

Hi I recently had a front composite door installed. The tradesmen were not able to do the adjustments sadly, they lacked experience (wont be using them again).
Door locks/opens and closes for now but its catching the lock slightly/stiff a bit.

My door has thinner and wider gaps along the door frame and door ie like this:

The bottom left is worse, literally no gap and above that it gets 3-5mm wide roughly. Anyhow its similar like this around the all 4 sides none of the lines are even.

So does this mean the door was not adjusted correctly? And I should see all 4 sides gaps (top, bottom, right and left all even?)

I am also trying to contact tradesmen to fix it, but they are unwilling since they believe the door is not installed correctly. So how can I check if the door has been installed correctly? Use a spirit level along door, frame and all sides to see if its level?

First thing is indeed to check if the door is level, upright and plumb... so a long spirit level on the uprights of the frame to check.its in upright and a smaller one to see of its actually level

Did this and its pretty much plumb in all areas, but I had a door fitter take a look at the door installation. He checked with an laser measure and found the door is off set and showed me the line/light going wonky and its not installed correctly, so this job needs an re-installation to fix the issue with any luck.

Had a feeling it was going to be this case.
