General Motors review: Poor, lengthy product allegation claims dept services overall lack of consideration and demeanor towards me

First of all, I was given an appointment to bring my car in on Saturday at 9 am and upon arrival, I was informed that they weren't even open on Saturdays! Both GM and Marburgers Chevrolet service were insensitive and just plain rude. December 29, 2023 I had towed my 2011 Volt into my local chevy body

shop to be reprogrammed/reset after a minor collision and question of recall on the hybrid powertrain control modules and crash data needed to be reset after the sensors detected a collision. This stopped the car from charging and prevents acceleration for safety precautions. This one-hour update has turned into over 6 weeks. My volt is still sitting. GM product allegation wanted pictures to present to "the team" and said I could get a loaner car 5 weeks into (non)service. The Chevrolet body shop says they don't have any cars to loan. their general manager, service manager nor service tech will return any of my calls. in the meantime, I am still walking to work, struggling to find ways to get groceries and canceling doctor appointments for my disabled fiancé, and infant grandson. My daughter is due to go into labor any day now while I am just frustrated, left to wonder when I am going to get my volt back because THE LONGER MY CAR SITS, THE TIRES ARE GETTING FLAT SPOTS, THE T-CELL BATTERY AND 12 VOLTS ARE STEADILY DRAINING. That is the absolute worst damage you can do to a car-letting it sit...It will have more $$ to spend repairs by letting the car sit opposed to the accident itself. I don't know what to do or who to talk too. Nobody cares. I asked to speak to someone other than the one I was speaking to all to be put back to the same voicemail.
