I noticed that one of the wheel trims was peeling off when I picked up my car from its second servicing two months ago (see first photo). I argued that this damage wasn't present before I brought the car in. I told my dealership that the issue might have occurred when they refitted the wheel trim, causing a "blister." However, they denied responsibility, suggesting instead that I might have used certain chemicals or jet washing, which I did not. I then complained to MG customer service about other issues with the outcome of the service, aside from the wheel trim. The Service Manager responded via email, still denying fault but offering to replace the wheel trim as a courtesy and to fit it when the replacement headlamps arrive (in another thread). The condition of the wheel trim has worsened over the past two months, as shown in the second photo.
