On the dealer report, it indicated that aftermarket products were put into the vehicle. The dealership was going to charge the same amount that I had already paid A-1. I ended up taking my truck back to A-1, and they denied it until I shared the report with them. They ended up having to repair the vehicle again. Yes, they fixed it, and put the correct parts on it, but no, I will not be returning. I guess they're honest, depending on who they're dealing with.

All they do is waste your time & charge you for it. I went in for a rear main seal that was quoted over the phone to me $1800. 2 days later upon picking up my car I'm told $1854 because I'm using a card. Later I find my card charged for $1918.89. They went a step further as to forge my name on a reproduced receipt to make it look like I approved additional charges. Not only that they didn't repair my car & refuse to refund my money. They want me to trust them again to bring my car back so they can really fix it now after less than a month of going there for the first time. NO WAY! The trust is completely broken. I now have to continue every few days to add oil to my car so my engine can stay in tact. These people didn't care whatsoever about the position they put me in. If a friend didn't see the oil running out my car in the garage after they supposedly had repaired it I wouldn't have known sooner than I did. This could have brought great harm to me & my vehicle. I took it in for a 2nd opinion somewhere without telling them that AAMCO said they fixed the problem, how about they tell me the same repair need to be done. I asked if it looked like something was replaced or repaired, they said no. AAMCO HAVE SOME TREACHEROUS PEOPLE HERE. PLEASE DON'T TAKE YOUR CAR TO AAMCO AT 796 HWY 20/81 MCDONOUGH, GA. YOU WILL BE SORRY! I will continue to warn people of this place. I'm working on getting my money back because I will never go back there again. So much for trying to patronize your neighborhood businesses. All I wanted was my car repaired, that's it! Even the customer service rep is rude! You never get a 2nd chance to make a first impression.

I signed and replied to the email and I constantly had to text to confirm appointment and time in which he did advise a day that he would come. I reached out Wednesday and Thursday in which he was supposed to come but never got a response, call or anything. I do understand and know you get very busy but this is not a good look and very unprofessional. I definitely would not recommend this company to anyone and I think you should look a little more into who you hire and them representing your company.

I tried to work with the owner of the company that I got in the accident with and Alpha and they could would work out the payment arrangement. Big mistake. I visited Alpha for the initial quote which I received. They were going to order the part and let me know when I arrived. I went back about a month later. They looked in the system, said that there was note and he said he would have to call me back. So I left. Another month went by and I did the same thing and left with the same result. My guess and its just that, the owner of the company that cause the accident and Alpha got together and decided not to work with me. I don't know. Only my mirror was damaged after a work truck crossed into my lane and decided not to stop. I filed a police report and I should have just called a lawyer. Lesson learned. Thanks for nothing Alpha. Too much time passed and now will have to replace my own mirror and I accept my mistakes for not stay on both companies.
