MiWay Insurance not fixing my car

I was in a car accident 31 Dec 2022. I'm insured by MiWay insurance. I put in a claim on the day, and they sent out a flatbed to tow my car to their supposedly reputable assessors and panel beaters. I had a courtesy car option on my plan, and they gave me a courtesy car to use for the 1-month period I selected on the policy until my car gets repaired. Two weeks down the line, no one from MiWay contacted me and i was getting anxious because I had two weeks left on the courtesy car option. When I called MiWay, they informed me that they assigned the claim to one of the claim handlers that was on leave by mistake and that's why no one called me. This to me is the company's negligence. So, this meant that two weeks was wasted and i would be impacted. So, they now assign it to a proper claim handler. Eventually the car gets booked in and is assigned to an assessor and in turn to a panel beater. I spoke to my claims handler Joseph Nlapho on the 9th Jan 2023 and he said that they (a previous claims handler by the name of Victoria) tried calling me on a number that didn't even exist in my possession and also, I called MiWay on numerous occasions updating my number to a new number, and if they claim that their calls are recorded, they should go retrieve the recorded calls where I've alluded to the changes made. The third week passes and there is still no work done on my car. I call the insurance back and ask to speak to the manager, and I spoke to a manager by the name of Keshni Shunmugan to inform them that I need the courtesy car extended as this is not my fault. She was very unhelpful and was determined not to assist even though the negligence is on their side. The 4th week comes and only then does the panel beater get hold of me and inform me that they will be starting panel beating body work on the car. I informed MiWay and they were still adamant to not extend my car hire. I was forced to give the car back after speaking to multiple MiWay employees (Pearl Kheswa, Keshni etc. etc.) February has come and gone, and I still didn't get my car back. This is two months that i am without a car. Eventually 1st week of March arrived, and the panel beater calls me and informs that I can pick my car up and its complete. I expressed my concern to them that I hope they fixed my car correctly as there was a hard knock as my car was T-Boned on the left rear. Avant Garde (as the panel beater appointed by MiWay) informed me that they not mechanics and they only panel beaters. I found that very shocking. When I took my car back, en route home there was a lot of issues that the car gave. Many errors picked up on the computer box, the car was smoking, and there were sounds coming from the back of the car on the wheel where the impact happened. I informed the panel beaters instantly and my insurance. After a week of driving my car, the sounds got worse and worse to a point that I felt very unsafe driving the car. I informed my insurance and told them that they need to uplift my car and take it to a proper mechanic which I appointed my own machinic (Ross Auto Duncan) as he is very reputable in the market, and I don't trust MiWay taking the car back to Avant Gard. I informed MiWay that this is their fault for appointing an incorrect assessor and also a panel beater whose workmanship is faulty and asked them that it's just right that they give me a courtesy car to use as I am the one affected and inconvenienced. I spoke to another manager by the name of Sello Matlala on *** and *** and he assured that he will take up the correct process to have my car fixed properly and have me a courtesy car. I've been waiting for almost a month for him to get back to me and every time he promises that his manager will call me to correct and every single day I need to call to no avail and every time Sello just informs that his manager will call me. There was a time that I had to pay for my car to go onto a flatbed to get my car to Ross Auto. Long and the short is that I am still waiting to get my car repaired properly in my possession and I still don't have a courtesy car in my possession while I am waiting for my car to be fixed. It is 3 months I am waiting. My policy number is ***6. I informed MiWay that I am leaving them as a client, and I am going to another insurance, but they need to fix my car.
