For completeness, I did write to the Chipsaway franchise and they reviewed it first hand today. Initially he agreed to polish out the rough marks (there and then) but claimed the gouge had happened after they had done the repair. I explained it was in exactly the same spot and has been there since they did the repair, however he is adamant that they would not have released the vehicle in that condition and that something had 'pushed it in' after their repair and that I had no way of knowing that wasn't the case!. I explained that the chances of it getting 'pushed in' at exactly the same place was extremely unlikely and wanted him to review the before and after photographs. On that note, for customer satisfaction he will sort it out as it is a 'very easy repair', however is not accepting any responsibility for its current condition as it wouldn't have left them in that condition. It's now booked in for rectification in a month.
