Rim repairs a nightmare to deal with

I sent my vehicle for repairs in mid March to a repairer which was recommended by the MFC innovation group for rim repairs the vehicle stood for more than 7 days upon receiving my vehicle back I then drove the vehicle and noticed that it was pulling to the right and upon reaching the speed of 80km/h the vehicle then began to shudder uncontrollable which meant I needed to decrease speed but because I pick the vehicle up at the time the repairer was busy closing I couldn't turn around and take it back, the following day I then contacted innovation complaints to discuss this matter with them as their repairer had quoted a substantial amount for the repairs and address my concerns to them all the while I had to get someone to take the vehicle back to the repairer and drop me off at my place of work, upon calling the innovation I had to explain myself 3 times and be transferred from one department to another without resolution eventually after hanging on for more than 30 minutes I dropped the call. After the vehicle came back from the repairer the 2nd time it needed to go to Ford because the repairer was unable to fix the alignment sensor on the vehicle and upon assessment they noticed the rims that was repaired was lighter than the other and said in selling the vehicle it would decrease the trade in value as this will be seen as work was done not well on it. I then made contact with innovation again and infuriated explained my situation also stipulating that I will not accept this kind of workmanship also I would not be able to take my vehicle back as I work normal office hours when the repairer is only available and since this is my daily driver I would need something to utilize in the mean time as the repairs won't be able to be done within one day. I then got a response from potso innovation group and she said that they unfortunately couldn't give me a courtesy vehicle or provide any assistance in getting the vehicle to the repairer even though I had stated to them when I opted to take it to a company of my choosing I was advised against this as only 2 repairers are authorized according to my policy to carry out the work which I don't see anywhere in my policy guidelines or terms and conditions, I also stated that this wasn't my fault I made this necessary arrangements to be without the vehicle for a specified amount of time and that the owners was on them that gave me only 2 options for approved repairs and now they are not willing to take responsibility the problem becomes mine I want this resolved I paid for the service to be done and I'm not willing to be inconvenienced again so I don't see why I need to stress and make the effort.
