Not happy with the service I received

I saw the toyota 1.2 XS advertised. I sent an enquiry, they responded the following day and even test drove the car same day with Duncan. I gave them my documents for car application. We agreed with F and I specialist about my monthly instalment thought I got a good deal. I asked for a copy of a contract so I can go through it, before signing the deal. They never send it to me in actual fact, Brandon came to explain to me that I was given a wrong monthly instalment on the wrong car. According to their F and I my bank approved me with a prime rate+1.86%. When Brandon came with a quotation “claiming its a podium”,my bank increased interest rate to 13.75% how I don’t know. I picked it up that I was gonna be ********** alot of money only to find out they even included extras on the principle amount. They didn’t explain to me about those extras, I saw them on the quotation.I can’t buy a second hand car that is equivalent to a brand new car Asoze..Im happy and at peace that I didn’t fall for this ****. They can keep their car and I will keep my money..
