Worst after sales

Worst after sales ever. The vehicle I bought from them thru a finance company has been given problems since the 1st day I took ownership of it. They were given the opportunity to fix it and still it is broken. All I want is the deal to be cancelled and them to come and fetch their vehicle. One of the Directors informed us that if we wanted a new car, we should have bought one. So, in other words according to him you should expect to buy **** for R200 000.00 so glad he could clarify that for me.
