Slow response on repair of motor vehicle

My vehicle was booked in on the 9th of February 2023, the parts for the repair only arrived on the 16th of February. As of today, the car was only sent for further stripping as it can only be done when the parts arrived at the repair centre.

Firstly, I want to know why did it take so long to order the parts for the repair, and secondly, why hasn't the repairs started when the parts arrived at the repair centre. If I didn't the do a daily follow up (up to 3 or more times a day), my car would still not be attended to.

Parts have been at the repair centre since the 16th of February 2023, and today (21st of February 2023) has something happened, a whole two days were wasted unnecessarily.

Calls to the repair centre take long to be answered, and feedback from the staff isn't very punctual.

Insurance companies need to reconsider where they send clients to have their vehicles repaired, as renew-it in general cannot provide the service as required by clients.
