How to fill gap between benchtop and wall?

I just recently had my benchtop installed and I’m very disappointed with the quality. They didn’t scribe it too the wall in the slightest and has left me with gap one up too 20mm in a section, the plan was to tile a backsplash and I’m curious on how I could make it work with a bow like this in the gyprock without cutting a section out to shim out the gyprock, can I just pack out tile adhesive? Or lather plaster out to pack it out?

Hi @smittyboi first up as the rest of the team have mentioned, is the installers. On the surface this is appears to be a stuffed their end on the measurements by a long shot. Failing that resolve, I would keep it as simple and clean as possible and use square quad to cover the gap. Its likely you wont find one of the right size, so white gap sealant will be required.
