International Panel shop, shocking customer service

Owner screamed at me and put the phone down when I queried why the rear bumper hadn’t been fixed with the rest of the accident damage and requested it be fixed. International Panel Shop claimed it wasn’t on the original quote provided to insurance but accepted to repair all damage based on images provided to them. Why would one ask for everything to be repaired except one part. Tried to quote me a further amount to repair. This panel shop misquoted me, then shouted at their customer and refused to repair further. ******. Definitely cannot recommend.
