Bad Service & taking advantage for 1st time buyers

I bought my car at Bruma Vw and it happened that I had a problem with my Fuel cap. I fought with them until VW had to intervene and suggested that we they replace it . I then went to them and they changed it but it was an incomplete installation, they then told me to come to them so that they can finish it . I refused because it was their mistake and I wont waste my fuel running up and down for their mistake. On the 27th Ragni sent me an email regarding the booking and we had an agreement that she will send someone to finish up the installation but that never happened . She called me on Friday saying her technician who lives around Soweto will come and fix it but as usually that didn't happen. No one bothered to call me or try to contact me as I waited for them the whole day.This is to show that They don't care, they like making empty promises & for them to sort your problem you must spend and fight before they can fix your problem. It would be nice if VW SA could monitor these guys as this is my 2nd complaint in 6 Months!As it is I don't want anything to do with VW Bruma
