Poor after service at NTT Nissan bloemfontein

I bought a Audi A4 during April this year at NTT Nissan bloemfontein, I am situated in De Aar which is approximately 330 km from Bloemfontein. From the onset the car had a sqeeking sound coming from the front wheels especially if one would drive through a dip or over a speed bumb, I thought I'll have it checked out during its service. After the service I was told that the control arms are worn out. I contacted NTT Nissan bloemfontein, spoke to Xander Du Plessis, brought the issue under his attention. Their response was that this is general wear and tear. I bought this vehicle cash and this is the after service I get from these people. I promised myself that I won't leave this issue, even if it is the last thing I take on before I die, please stay away from NTT Nissan bloemfontein
