Southern Comfort Auto A/C

This is the worst experience ever! One afternoon after using my heat that morning on my 2007 Nissan Maxima I flicked on my a/c and noticed it was blowing hot air. I took my vehicle to PepBoys for estimate. They adviced there was a leak within my air compressor that needed to be replaced. There estimate came to $707.00 which I at the time felt was too high. The next day I researched online for cheaper mechanics per reviews on Google. I found Southern Auto, viewed their website where it said they "specialized in a/c repairs" I took my car to them that next day on January 22, 2014 and spoke with [redacted], I told him my a/c went out after using my heat one day and it was blowing hot air I told him Pep Boys said I had a leak in my air compressor and wanted too much.. He said he could beat their price and came up with 689.00 and said he would have it done and working that same day. I was liant because it was only a few dollars less than Pep Boys. But I allowed them to fix it. That same day it was fixed I checked it out when it was completed and noticed my car was reving up after it was cranked as if I was pressing on the gas pedal. I immediately had [redacted] look at it and he advised the compressor was adjusting to the cold tempature outside because it was cold that day. I drove off and when I got up the rode I stopped to a stop light I heard my car making a really loud noise I had never heard before. I immediately called [redacted] who advised me to bring it right back. When I pulled in he came I let him hear it and he said his mechanics over charged the compressor in a matter of minutes the noise was gone my a/c was fine. A week later I got in my car turned the a/c on and it was back blowing hot air, I called and spoke with [redacted] alerted him of the issue and said to bring it right in I did once again he fixed it to run back cold. Now 2 weeks later the air is back hot now Im upset I called to complain and [redacted] became argumentative saying Pep Boys estimate could be wrong and he didn't even do a a/c check
