Computer Outlet

9/2/16 brought my lap top in for service the screen was black. He said that it was the motherboard and he had the part. Charge was $229.84. Again on 10/24/16 screen black again. Took it back and he charge me 95.84 he claim it was the chip. Once again on 1/5/17 screen black again. This time I took it to another computer repair shop. I was told that it was the motherboard. They ordered the part. Computer outlet put in used parts. They won't give me my money back because they said it was a 30 days warranty on the part. I told them this is not about a warranty this is about poor workmanship and using use parts. All together the time was less than 3 months. They have engaged in the worst form of gamesmanship to achieve their own goals. I went there in good faith and got screwed by this company that should not even be in business.
