The poorest service I have ever received in my life!!!!!

So my car has been with Renew-IT Rivonia for over 3 months since July. No complains since I could understand it was a pandemic and imports are probably slow. I get my car on the 27th of October, only to find dents and the undercover of my car smashed and not fixed. Bring it up with Renew-It Rivonia and I am told they did not receive authorisation for those repairs. I call my insurance and get an all in authorisation from them. I ask Renew-It when I can bring my car in and am told they will let me know as the part has been ordered and not delivered yet. A week later I ask again and I am told I can bring in my car on 05/11/2020 and that the repairs will take a day to fix. I deliver my car and am told by Brendhan that they will provide feedback to me at about 11am same day. 11am comes and goes and I still hear nothing. On Friday Morning I enquire about the progress and If I can collect my vehicle, I am then emailed back to say the insurance did not approve the dents but they should be done with the covers later in the afternoon. At 12pm I ask what time I can fetch my car, and I do not get a response through out the day. I then called and was told Brendhan is busy and will call me back. Needless to say that never happened (I have called a couple of times and always got that reply and then never got called back) So at about 5pm on Friday I get to Renew-it and I am met with "Your car is not fixed, obviously because the part is still not delivered yet" from Brendhan. When I ask why I wasn't updated cause I called and emailed, I was told he was very busy with Discovery. He then confirms to me that my car should be finished by tomorrow 10:30 am definitely as they expecting the delivery in the morning. Saturday at 10am after not hearing anything from anyone, I email asking about my car and I am told Harriet was supposed to contact me to let me know that they are still awaiting delivery. Harriet calls me about 10 minutes later to let me know the part hasn't been arrived. I am not impressed because at that time I could have been on my way to collect the car already and Harriet goes on to say she doesn't know why I wasn't informed in time. Monday comes and goes and I hear nothing. Tuesday 3pm I ask for feedback - any feedback at all! And I get a reply at 5pm that the part arrived on that same day and they should be completed by 9am on Wednesday. I ask for it to be delivered to my house as I was on sick leave with Flu and I am informed it will be. Wednesday comes and goes and 5pm when I still hadn't received my car yet I email enquiring. Brendhan then replies on Thursday and goes on to apologise for me not being advised about them being unable to deliver the vehicle and that he has the drivers booked to deliver the car before midday. Fortunately my car arrives at about 11am today (Thursday). Now I go on to inspect it, only to find only one part has been fixed and the other that I was seriously worried about as it makes weird sounds while I am driving has not been fixed at all. The drivers don't know anything about this and I tale one of them on a ride to let them hear why that part is a problem as it makes a lot of noise when I drive. I call Renew-It Rivonia and I am told Harriet, Veronique and Brendhan are all busy and I should leave a message (remember this happens everytime I call) So no I refuse to leave a message and said I will hold. While I am holding, Veronique calls me and informs me that the drivers are there for me to take delivery of my car, when I tell her my car is not fixed she said she doesn't know anything she will get Brendhan to call me and explain. When Brendhan calls he then says he has just been informed that that one part was not received therefore not fixed. So here are a few questions; 1. Do you guys employ a ask or stay in the dark policy where if your customers dont request feedback they just wont get it??? 2. Why did I have to wait a week to get an appointment to bring my car in when initially I was told it was because you waiting for parts but I still had to leave my car with you for another week because "YOU ARE STILL WAITING FOR PARTS???" Brendhan himself told me the part was only ordered on Thursday (the day I brought in my car!!!) 3. How, how do you not know until the car is delivered that the car was not completely fixed??? This makes me worried about the quality control, now I am wondering what else on my car has been overlooked??? Because apparently nobody checked my car, NO ONE??? To the extent that I had to be the one to say my car is not fixed to the people who supposedly fixed my car!!!! 4. How do you Brendhan expect me to just accept that flimsy excuse of you only finding out 10 minutes ago that my car was not fixed??? When everyone says Brendhan is the person working on my car but even Brendhan himself doesn't know what has or has not been fixed on my car????

Today only I am being told about how one part hasnt arrived and they have to wait for 21 days to receive the part then the fitment will be arranged. Today!!! When my car is at my door step and I am refusing to take delivery of it because it is not fixed!!!! Now who wants to guess how many emails and calls I will be sending to Renew-it Rivonia just to follow up on the part and to get an appointment to get that part fitted on to my car??? Yes, pathetic I know.
