Scratched TV after repair..

I took my TV in for a repair in Montague gardens. They quoted me R1800 for the power supply for an 47\ SL80 TV. When i paid for the repair i asked them if they would kindly look at tape surrounding the front glass on the TV.<br> <br> When i collected the TV today the tape was repaired like I asked but the Glass has many scratches on it. It's definitely the inside of the glass whatever they used to clean the tape. The TV is now lying on my dining room table and don't really feel like setting it up it looks terrible. <br> <br> I do appreciate all their efforts for the repair but now i'm stuck with a scratched TV. I am now a disgruntled customer. "
