Mintys Tyres - Scratched my rim and didn't balance tyre properly

Mintys Tyres Umhlanga Good - Neat place with friendly staff. Bad - May have been my bad luck, but I visited them about 2 weeks ago for 2 tyres. Unfortunately when I got home I noticed that they scratched 1 rim, about a 20cm long scratch on the edge. I did see the guys gathered around the machine at one point as it seemed something broke, didn't realize it was my rim and the machine had scratched it. They obviously noticed but didn't say anything. Too top it off, since I use side roads to work, I only realised on the weekend that they didn't even balance the wheels correctly. Got them re-balanced properly at Hi-Q. Quite disappointed with the overall experience. Wasn't going to post this, but you rather double the workmanship.
