still waiting for claim to be finalized

Had an accident on 16 September 2023. I have been getting a sms that the vehicle is booked for assessment and then a few days later its been cancelled. This has happened more than four times since the accident. Since the accident to date the vehicle is still awaiting assessment. It is now almost a month with no vehicle nor finalization of my claim. How long does it take for an assessment report. I am so highly disappointment, i even regretting getting my friends and family joining discovery insure. I have spend so much money commuting. I want my claim to be finalized asap.
