Bad customer service Renault Clio The Glen

I bought a Renault clio from Renault The Glen. I am absolutely disgusted by their service. I bought the vehicle in November 2017, this vehicle is giving me alot of issues of which I called the dealership and reported those issues. Till today I have not received any feedback. I was told the vehicle is out of warranty and that I will have to fix the vehicle myself. How is that possible?? I been getting the run around from a lady named Ferriel, her colleague leroy who works in the workshop. Last week I was contacted by a guy named Hendrick, I once again told him what was happening with the car. He told me he would call me back. I'm still waiting. It's also due for a roadworthy test of which the dealership is responsible for. When will I get assistance?? Such bad service. Absolutely disappointed. Please do not purchase a second hand vehicle from Renault Clio the Glen
