Worst Service from Samsung Repairers - Liptronics

I have taken the Samsung Microwave I bought from Homechoice to these people since it was 6 months old and I have gone back to them for fixing it about 9 times, this is according to the Job number stickers on the Microwave, they have failed to repair it 9 times and I am on my way to them again the microwave stopped working in just 2 days after it returned. this is sickening service
