Taking too long to fix a car with minor damages

My vehicle was booked into Sanrose Motors and Panelbeaters by Momentum STI on 2 May 2024, after the claim was authorized on 20 Feb 2024. The vehicle has surface damage and scratches after a tree fell on it and is in a drivable condition. Sanrose have taken exceedingly long to complete the repairs, and 25 days later, the vehicle repairs are not completed. Sanrose is also poor with customer service and communication. We have phoned them on many occasions for updates, and the relevant person responsible for our vehicle, Lizelle, is never available, and promises that she will phone back are never met. This kind of customer service is unacceptable. We would like the repairs to our vehicle to be completed and returned to us ASAP. We even went to Sanrose on the 22nd of May to check the progress and we were promised that we can collect the vehicle on the 24th. That promise was not fulfilled.
