S**** selling company

I am done with this company, I am trying to reach their customer service but the phone just keeps on ringing. I bought a brand new Renault Kwid from them but the thing keeps on breaking and they not fixing my problems. Please help me get hold of them because I would love to give their s**** back to them. This Message is for Renault Kimberley, Bloemfontein, Head office and their ****py customer care.
