Mannequin X 2022 – Unable to get a appt to repair defects

I bought 2022 Model X after one year of wait time. The dome light inside the car has never been working and the appointment has been rescheduled around 7 times because of part not available. Is there a way to talk to somebody to have this resolved? Nobody seems to know when this might get fixed. It is already over 6 months now.
