Wrong Car, Wrong Price, Wrong Deal

I bought a Polo Vivo 1.4 Blueline with cruise control but received a Polo Vivo Blueline without cruise control and was not made aware of this. The sales manager also decided for me that I should have a Linked interest rate and not been given the option of a fixed interest rate as according to him I could not afford it. I reported the car did not have cruise control the day I received the car and was told I have to pay in R10 000.00 to have the cruise control fitted. I also reported that I did not want the linked interest rate on the day I received the copy of my contract which i was suppose to receive within a week but didn't and i requested a copy a month after receiving the car. I was told by the Customer Service department of VW that I had already put pen to paper and that I couldn't do anything about it. I'm now sitting with a new car that's aircon worked for about a month and no other dealership is willing to help me as I refuse to deal with Alberton.There is NO service with VW! I dont want to hear from the Alberton Dealership as I have heard enough excesses and was promised feedback from the FNI which also never happened. I've had my car 2mths and payment has gone up already
