Worst service

Would not recommend, using this repair centre to anyone, worst service I have ever received. Took a Samsung Tv for a repair, T.V was operation but would switch off randomly on its own. TV was received by repair centre and I was quoted R1450.00 for the repair and I accepted and TV was fixed, upon receiving the TV I went home and connected it and yet again the same issue still exists with the TV, I have returned it and yet again was quoted R1600 to replace another part in the T.v, after numerous attempts (about 5 or 6 times) to try and get ahold of the manager no success. I personally arrived at the store and yet again he was not available and niether did the staff assist. So I am stuck with a TV that was not repaired for the original fault
