BAIC X55

Bought the car in September, yhe car was delivered with 1/4 on the tank (delivery costs were R5700 to be exact yet I didn't qualify for a full tank).I was promised to be reimbursed but we on the 3rd month now with payment.I had to do the license registration myselft, I spent about R1100 and submitted my proof..I'm still not paid, its always the story that they have submitted it to Joburg and payment is on the list..the admin is failing us
