Discovery, net assess and fleet vip solutions bad service delivery

I am receiving absolutely poor service from Discovery insure, their assessor company net assess and the panel beater they sent my car for repairs fleet VIP solutions. I had in ancident in December 2022. My vehicle came back with a problem I reported immediately. Its a back and forth situation with no solution. Its been 3 months and I'm still having to drive my car with this problem. Neither party is taking responsibility for their lack of service. I have requested on numerous occasions for a courtesy vehicle and this is when everyone goes silent. The panel beater inconvenienced me by not repairing my vehicle as they should have. I have to constantly take time off from work and find my way around if I do not have a vehicle. They requested for ne to bring my vehicle in on Tuesday to fit the parts that they did not fit and was quoted. I asked that they arrange transportation for me to and from work and they went silent . And to do yet another wheel alignment which does absolutely nothing to the problem. The vehicle has a pull to the left. They advised there is no physical damage so how is an alignment going to help if they don't do an actual check. Why are they not checking the Tie rod ends, rack ends, shock and control/V arms
