Beading/strip fitted incorrectly at Mercedes-Benz Menlyn

In September 2020, I took my car to Mercedes-Benz Menlyn for a replacement of a beading/strip covered under warranty, I waited for 4-6 weeks for part. It was finally fitted early November but fitted incorrectly, I was concerning that the fitted unit was different to the other factory fitted unit on the other side, the new fitted unit was visibly out of the line.

I took the car back but the dealership provided the following response; (after months and months inspecting the car and at some point referring to Approved panel beaters)

"As per my email below, kindly see attached report from Mercedes Benz South Africa

The technical case has been concluded as per MBSA technical and ABRC (Mercedes Benz Approved Panel Beater), there is no further form of adjustment that can be made to the beading as it is only clipped into place. There is always tolerances as far as trim fitment/panel gaps replacements for example"

I immediately lodged the complaint (CS-***) with Mercedes-Benz South Africa and my matter assigned to Alli Bey never came back to me.

I then took the car to Renew-IT Bedfordview for an unrelated repair but requested their technicians to also have a look at the beading/strip fitted at Menlyn Mercedes Benz. To my surprise, this Mercedes Benz approved repairer confirmed that the beading is fitted incorrectly. This confirmation comes 9 months later after I have on a number of times tried to explain to Mercedes-Benz Menyln that the strip is off the line and should be replaced
