Renew it Rivonia bad service

After the accident, Miway blink booked send me to Renew it Revonia blank to get my car fixed. Communication with Renew it started on 31 May, but they could only book in my car on 26 June and was promised that it will take 15 days to fix my car or 25 days if they discover extra damages. After 25 working days, I decided to go to Renew it to check the progress only to find my car stripped with dents and a broken mirror hanging. It's been 35 working days and I still don't have my car. When I call I do not get straight answers, my calls not returned most of the time. Now I was promised that I will get it on 14 August but now when I tell them that I'm coming to get my car they don't give me straight answers
