Repairs not done after a month

On the 28th of September I had an incident which left my gearbox damaged. This was also confirmed by Outsurance after an assessment was done. Throughout my claim I've had to fight with Outsurance for feedback, eventually their representative Portia Mtembu confirmed that once the car is with the panelbeaters, Outsurance is not liable for continuous feedback. This is a fact I didn't understand because I'm their monthly paying client not the panelbeaters. It's been two months since the incident, my car is still the same condition it was when they first took it if not worse. At one point I was advised that the repairs are completed but when I went to fetch it, the paint work was not satisfactory and had to leave it for repaint. On the 13th of November I went for the second time to collect it, on my way back from Impact panel beaters it got stuck. I've been assisted by a very professional and friendly lady at impact panel beaters Rhonda but unfortunately the technical staff haven't provided me with a clear explanation of what is wrong with my car. My car is now with Mayfair gearbox who have advised me that the car got stuck because the panel beaters returned my car without putting oil, the fact which the panel beaters are obviously disputing. As I'm typing this review, I don't know what is wrong with my car and when it will be returned to me, Outsurance is not assisting they keep on telling me what Mayfair and Impact are telling me which is nothing.
