Lying dealership

I will never buy from this Nissan again in my life. I work in Standerton but I am from Heidelberg Gauteng. When I bought my NP200 I used my Heidelberg address because I wanted my vehicle to be registered in Gauteng. I was told by the dealership that they will send their driver to Heidelberg. But every time he had to go to Heidelberg he was allegedly sick. My temporary licence kept on expiring. They even gave me their trade plate. At this point I was just frustrated with them. Then they asked me if I could assist them by gong to register the vehicle myself. They would refund me. I did all that and send them the registration slip, the plate number slip and my petrol slip. They only refunded me for the registration and plate numbers. They never refunded me for my petrol. Poorest service of my life.
