HATFIELD HAVAL MIDRAND

I bought a vehicle which was advertised with all the specs I wanted. I didn't see The fine print stating specs for new vehicles. I contacted the sales man Henrico Albert's and he said they will fit a camera. Afterwards he said I must pay R6000 for it.i reported it to the MIOSA, with no joy.i emailed the Dealer Principal Mr Diederik for a meetingwith him. He read my email and ignored me. Please can someone help/ advise. I have a disability and the camera is of utmost importance to me.
