Run Around For my refund

my name is Florence kekana,i went to Hyundai east rand on 30/06/2015 to trade in my mazda5 and get another car, assisted by aaron khoza,who told me to pay r500 deposit inorder for me to test drive my car the next day and told will get it back same time if I don't like the car,i paid the money and went back on the 01/07/2015 and didn't like the sheer driving of the car,requested for my money was told the finance dep is closed for my refund,been going there since the 1st then on the 6th july spoke to their manager SHAN or SHANE who told me he didn't know about this he will make sure I get my money on the 7th july he will send a driver which he never did, I had again to go back on the 11th july that is when I got my cheque and nothing no apology was given to me, I want Hyundai to re-eburse me for my petrol used for the run arounds and my airtime calling the for my refund, I have again sent an email to BRUCE NICHOLSON who is apparently their regional manager still waiting for their response but my compensation I want it.
