Castro Auto Repair

Castro Auto Repair shop is the worst company I have ever been too. I have a 2007 cts I took my car to this location for repair. Up on arrival I talked to Manger/owner about my problem he let me know he will get to the bottom of my problem let him have his workers take a look to see what's going on. 15 mins later he let me know that I will need to replace my drive shaft supporter that why I'm having a knocking noise coming from the rear back area of my car because the drive shaft is shaking! About $180.00 I will take care of your problem that includes labor and parts so I said go for it. 4 hours later my car was ready everything was good. 45 days later the knocking started back I return back let the Manger know I'm having the same problem again his worker check the drive shaft out after he put my car up on the rack I notice that the drive shaft bolts was loose. Worker tighten the bolts up after that he went and got his Manger/ Manger inform me that the drive shaft supporter needs to be replace again.. I ask him are you talking about the same part that you replace that I paid you a 180.00 to replace he said yes I ask him how in the world that the part you replace go bad that quick he inform me he didn't replace the part with a new one it was a use part my point is he didn't let me know he was using a use part on my car at the time he repair my car i feel if the part was new i will not be having this problem now he should let his customer's know if he will be using use parts on their cars now I'm stuck again I feel like he trying to make a quick buck and he's get over on his customer's. he want me to pay him 180.00 again he wasn't concern about the problem any more when I told him i was upset because i didn't have a problem with paying he shouldn't have a problem replace my part with a new part not a use one and I shouldn't have to pay him again!
