VW Caddy 2021 - No ETA for parts or repairs

My car was in an accident on 22/10/2022 and towed to a panel beater in Mossel Bay. After a few days the claim for repairs was approved on 26/10/2022. Almost a month later I was told by the panel beaters that the car hasn't been worked on yet and that a part is on back order so I would only likely get the car after the Dec/Jan holidays around 10th February. This in itself is unacceptable. Today I was informed by Outsurance that said part now has NO ETA... I realise that the part issue is not that of Outsurance per se, but the panel beater on their panel is shocking and therefore Outsurance is shocking. I really don't know what to do next. VW Caddy 2021 with less than 24 000Km on the clock, bought new.
