TV repairs total disaster!!!

I had my TV fixed by these guys last month which has now gone worse again and im still waiting for them to come fix the mess. Total disaster!!!! Guys are completely unprofessional, they come with old used parts and damage your TV even worse using 'not original' parts. I had the whole board replaced with a second hand old part that i paid R2200.00 for. Have I gone to a professional company I would have had it fixed properly. My TV went from being a JVC to a Telefunken with poor quality display. The workmanship is extremely poor. I would never ever recommend them should you need a professional company to come fix your TV. These guys cannot fix TV's, take my word.
