Extremely bad service-ignored messages and calls

I went to automagic zambesi on the 19th of january to get a quotation for my renault megane, i was told that the quote would be sent to me on that same day, until today 23 jan, i still havent received a quote. I called everyday and the receptionist told me that armani or steven the manager will call me back as they were to busy to deal with clients every single day. Today i called again and again the receptionist gave excuses and later started shouting at me saying i should stop calling. If automagic zambesi does not have time to take in new cars then they should simply refuse to quote instead of wasting customers time! I have never experienced service like this in my life!
