Business ProfileforJupiter Chevrolet LP

On 2/11, I called OnStar as my Telemetry module stopped working. OnStar tech ran a diagnosis on the system and said that it was bad, gave me a ticket number, and told me to go to a dealership for service. I have been using Jupiter Chevrolet for other service needs as they came from word of mouth. I went into the dealership on 2/12. The tech said it would take five days for them to run tests, but told me that when I pulled in, they already knew what was going on then when they plugged in the *** reader and pulled the codes.I brought back my vehicle that Friday- 2/15 for the service, I was out of a vehicle for 5 days, not including the weekend. Finally, after a few unpleasant phone calls with an incompetent service writer *****************************, who set my (the customer's) Expectations of time, started Gaslighting me, saying he never said anything like that a few different times during the phone calls. Finally got my vehicle back. Late on a Thursday afternoon, and was told they would need to order parts. No problem as I knew the Module was back-ordered.I was talking with the service manager *************************** after my incompetent service writer ***************************** complained and said the part should be there on Wednesday 2/21 and he would call and let me know, guess what- no call. During that conversation with the service manager ***************************, I had asked if I could wait for my vehicle and I was told that the repair would take 4-5 hours, but was okay to wait.When the part finally came in on 3/4, no call from the service manager ***************************, as he said he would do, instead some girl called and told me the part was in. I had asked her the same question, can I wait for my vehicle, she said No, that I would need to drop it off again, and this was after the service manager *************************** said I could. Even after I told her what the service manager *************************** said, she said no, *************************** never said that. Again, it seems like the gaslighting runs deep in this dealership, she even called me back a 2x and told me that the service manager *************************** never said that as she went and talked to him about it.I have made calls, and email with no response, my last call to the dealership was on 3/7, talked with another service writer (not sure of the name) who said after 10 minutes on hold that the service manager *************************** would call me back, nope, never happened. All of this time, my vehicle is broken, I have a check engine light on, features that worked when I took my vehicle to them, but now don't work. I am not getting any calls back to schedule a time for service, no email responses.
