Mastercars Claremont Disgusting Service

My wife bought a brand new Polo 1.0 Comfortline last year, besides the car being recalled for manufacturing checks we were still happy. At their end of financial year sale, we visited their mastercars division and was interested in an Amarok bakkie that was on sale for R220K, after my application and further queries regarding some faults I've identified e.g. Roof had water leakage and a seat that had to be fixed. It took these guys almost 2 weeks to get back to me. I called almost everyday and was given the runaround for all the times I've attempted contact. Eventually after I called I was advised that my offer to purchase has been declined.... I didn't give this amount to them.. They gave it to me... I was approved but now due to their mistake I can not purchase the bakkie...??? What is this??? I was so discussed at this and tried to speak to someone higher only to find out that service becomes even more appalling... Shaun Spaans, sales manager told me over a conference call that I must stop as HE told me he won't sell the bakkie to me... He felt he had the right to disrespect me as a potential CUSTOMER, "TAKE YOUR BUSINESS ELSEWHERE"... this was disgraceful, never have I experienced such disgusting customer service for something that wasn't even my fault....I had to mention to the principal dealer Bennie that I didn't even get an apology from anyone.. and for the first time through all of this he emailed back to say that he apologised, and that was it.... Disgusting!!!!! ????
