Ross Champion questionable tendencies experienced

The car went in for repairs early September for full repairs. On collecting the car discovered that the car had a part still not replaced and a clumsy workmanship on bootliner not intact so loose. I immediately highlighted to them before I left with the car and was promised the part will be organized and replaced. Everytime I follow up I get funny stories at some point another person took my call and followed up and the feedback was the part is not showing in the system as on order after a while following up this surfaced. Now it is almost mid December still waiting for the part and I am being referred to Honda of which that part has to be managed by Ross Champion. The concern I have, full payment was released by the Insurence when the car was collected whilst this work was still outstanding implying that for them this is no more value add to Ross Champion as this comes with no payment. This is a poor service where the customer comes after Ross Champion's needs. Utter dissapointment it looks like to get this done will be next year some time 6 months or more later. Their service has gone so poor even regarding updates which is further confirming they have no interest in the outstanding work closure.
