Pathetic service from evaluater

I must say your service is pathetic,I asked for someone to come and see my car .And the guy came here without asking me any permission another guy took a machine and plugged it into my computer box.Asked him what he doing he said checking for error codes.I said to him without even asking me he said it protocol.Then he said they can't purchase the car as they only buy original cars as they sell to dealers .I said to him all cars even new ones get scratches so what does this affect a sales the car was not in an accident.This guys attitude was pathetic.I guess that is why we buy cars is bigger and better then this brand that is part of the Tele sure group.
