Renew it Edenvale gave bad service

I am very disappointed and angry with renew it in Edenvale area. I got an accident in January 2018 ,my insurance took my car to renew it since they are the mercedes benz approved panel beater .After waiting for such a long time for my car thenveventually i got it in march 2018 .I figured out they didn't change the tire that was involved in the accident I asked them to replace and they told me they do not have the tire but they will order.. i took the car , few days later of driving the car i started hearing sounds everytime i turn to the left hand side which is the side that got damaged duting the accident. I called them and they say I must bring the car when I got there I waited and waited by the time they were suppose to help me they telling me their workshop guys are going home I must come some other time but I insisted they find someone to check my car because I wasn't comfortable driving it with that sound..then the workshop supervisor decided to check himself .He drove the car to the workshop I waited in reception..then few minutes later he said he can't find or see anything wrong because everything was replaced.He mentioned since I'm waiting for my new tire from them as soon as the tire comes he will strip the and check again before installing the new tire.Eventually after a month they called me to let me know my tire has arrived.When I went there now they telling me to go to tiger wheel which was their nearest place they use to install new tires.I told the supervisor that's not what we agreed on , I said they promised to check why there's a sound then they replace the tire.The supervisor kept on saying they do not fit tires and the guys who are going to fit tires will check for me where is the sound.I eventually went to the tire place to fit the new tyre but I could tell the guys there are not mechanically they also couldn't tell where the sound is coming from.and the guy who was helping me by the name Chris said he doesn't think it's anything serious he put some spray and he says maybe it us just dry.Then the sound for some reason went quite. .few days later the sound started..I decided to take my car to the dealership and explained my story and that I'm not getting help from the people who repaired the car.They checked and they responed they noticed the bearing, shocks and shaft were never replaced and they are damaged.They sent me a quotation of things to be required and photos of the damaged parts. The sad thing is that this is the side that was involved in accident and I went to renew it couple of times telling them there is a sound as I turn my steering to the side they fixed and they couldn't help me...I'm suprised how can they be one of the approved panel beaters for such a big company such as Mercedes benz if they are going to fix cars like this..even worse lying to me that the car was fixed correctly were as it was not.

This could have cost me my life.

They do not have the decency of even trying to help me and they were hiding behind the tire that needs to be replaced. I had to go and pay Mercedes R1200 for checking my car where as renew it was suppose to check properly for me.

I want the R1200 I payed mercedes for the job they had to do...and I need my car fixed to mercedes standard with brand new parts.
