I had to have an alternator put on my car there. I bought the part myself so I wouldn't have to spend as much money. My grandma helped me pay the mechanic to put it on. Then we got it back and it still wasn't fixed. The guy said we bought a bad alternator. So I had to go buy another one, and pay the guy again to put the alternator on a second time. I took the orginal one I bought back to the shop I bought it from the get the money back and they tested the part and said it was perfectly fine. They gave me my money back but said the mechanic probably blew the alternator when he put it on. I talked to my cousin afterwards too and he said it's very easy to blow the alternator if you don't do it right. So I got charged twice for their mistake.
