Highly Unprofessional with a very bad service and customer care

I took my car Renault capture for a service at Renault northcliff on the 25th of September 2019 expecting to get it back same day, they told me there is a part that need to be replaced I will get my car in few days, after 2 days I was called they said they part is not available anywhere in South Africa they have to order it from france which will take 10 days I will then get my car in 15 days, I was given a Renault kwid with a broken windscreen. I did not complain hoping to get my car in 15 days, after 15 days they did not bother to call I had to go to them, only to find that the cat is still there outside on the sun not fixed, I escalated the matter to the manager later then to service department manager at Renault South Africa they both did nothing. They said there is nothing they can do. I requested a bigger car since I sometimes travel province to province and kwid is not safe especially during windy and rainy dais, they said I should pay them 1500 to a bigger car as if I am the one can't do my job. Customer care they said they sympathize with me, that's all they said. Apparently France doesn't have parts as well, I don't who should. Meaning world wide the part is not available that's what they said. Until today 11 November 2019 my car is not fixed. If you want to be safe avoid any Renault care, if you owning Renault car good luck. U want to take ur Renault for service avoid Renault northcliff. They must just close the shops. U can't run a car dealership like a ****a shop really!!!
