Shocking Service and communication

We have been with Miway Insurance for three years now. On the 12th of October 2023, we were in an accident for the first time since joining Miway Insurance. Their response to the accident was swift and very helpful - thank you for that. We collected our AVIS rental as well and everything went smoothly. Our repairs was assessed relatively fast and they were approved within 14 days. On the 6th of November we received an email from Miway Insurance that the Panelbeaters are busy with their final repairs. This is where our experience went downhill. We phoned the Panelbeaters to enquire about our excess payment, since our vehicle's repairs were almost finished (according to Miway) and they informed us that they have not yet started any work on our vehicle, since they discovered additional damage and they are still waiting on approval from Miway Insurance- needless to say we were shocked. We have since had to return our AVIS rental, with no other means of transport, our vehicle is still not repaired and we have made numerous phone calls/WhatsApp enquiries to Miway Insurance, with absolutely no response/updates on our vehicles repairs. Every consultant we speak to promises to get back to us as quickly as possible and then they just never do. We are really shocked and disgusted in the lack of Service and communication from Miway Insurance. We have made 4 phone calls, started 4 chats on WhatsApp, spoken to a total of 8 consultants in the last five days. What more can we do?
