I have had a few problems with my Tesla 3. The passenger seatbelt would not clip in. All service requests are done through app, and they seem to get back to book the car in. The technician was sent out to me, which 2 weeks I could not take my car in to be looked at at a service centre. Now my car won't lock, and again I can't get anyone to schedule a time to have it looked at. I am looking to sell the car less than a year after getting it due to bad customer service.
