Frustrated and very disappointed customer

The division of Nedbank is MFC.The service I got from them was so s**** that I would never refer a friend or family ever again to MFC. Their principals,their morals and what they say is not according to what they do. I have a vehicle that is not road worthy which bought from Renault and I brought it to their attention. They said that they will sort me out within seven days. It took them 25 working days to get back to me,which is not acceptable. I left numerous of different contact numbers to contact me and the excuse that they came back with is that they couldn't get a hold of me. This is how unprofessional MFC is. Secondly is I bought the vehicle from Renault. The day I bought the vehicle I have been having problems with my airbag light.Meaning that if I meet an accident, the air bags will not be deploted. On numerous occasions that I tried to resolve the problem, they fixed it and when I jumped back into the car the light comes on. I got a life cover policy and I am driving a vehicle that is not road worthy, if something has to happen to me, my life cover will not pay out because the vehicle was unroadworthy. Then I went back to Renault to the Manager Bradley Singh.Then I went to the Salesmen Neresh.Then to the Workshop Manager Adrian. I got the job cards to show how many times I have been back and forth. Then I tried getting hold of the Dealer Principal Louis Pereira and still can not get no joy. This is the service I get from Renault. The manufacturer when you call them, they also giving me stories. It is shocking that I see a group as Renault that can not even sort the problem out. The Dealer Principal at Renault Durban is never available and there is a guy Adrian, when I spoke to him, he tells me don't worry will get back. It has gone months not even a call or any communication from them,this is shocking. I will suggest this to friends and family, please do not buy from Renault Durban because the way they handle customers and the way they do business is not ethical. The second thing is MFC is useless, same like that of the dealership Durban. The Dealer Principal is never ,never, never there to take a call or to sort a problem. I wonder why he is called a Dealer Principal but is never at the premises. I have spoken to friends and family in the last three years which I had made referrals to Renault Durban. Going forward I have put this on Hello Peter to make people aware how ****py service Renault Durban, Renault South Africa and MFC as the finance institution. They don't even know their elbows from their nostrils. It is disgusting to deal with this type of people.
