no satisfactory

I traded in 2 vehicles in as my Audi was to expensive to run. So I was told that my shortfall was very high and as I could not pay the shortfall sales person said the only way to get out was to devide the shortfall amongst 3 vehicles. So said ok as long as the repayment is affordable. Lenny sales pre ownd said not to worry he will sort it out for us. After some time they said we can Come and sign the contract In the meantime the instalments was more than we expected as we were not informed of the total amount. Lenny and fni management said I should come back in 3 months, so they promised to us they Can trade in the 2 i10s for a single vehicle, but ghen Lenny change his words and said he can't do it as my settlement is high. When I took delivery of the vehicles no inspection was done by sales person, 1.my hyundai accent had no spare tyre rust and no paint in the boot, 1. I10 has has a misfiring issues the pinetown branch took 4 times to repair my vehicle. As I had to drive 4 times from hillcrest to the pinetown dealership for the same issue I no longer had money for fuel, I asked workshop management to compensate for fuel, he said he will do it. When the drivers delivered the vehicle to watercrest mall. There was no fuel in the vehicle. I have been trying to get the spare keys for I10 over 8 months now, I went back to hillcrest branch, collin the supervisor said that he will get someone to call me yesterday for the keys, still call.
