Empty promises

I purchased a car in audi mbombela early last year, it's a used car they sent me pictures and everything was in tact, then day before delivery of the vehicle the then saleman mr Werner called me to notify that the car sticker the one that describes the model of the car had fallen off and promised to fix it and told me it was gonna take e months as they are ordering from France, after 3 months he told me stories it was no longer France he sad he went and ordered stickers and promised to deliver which he did, i was not happy with the product as it was made out of rubber not ***** as the original, i sent it back and never had from him ever since, then later decided to follow up with the manager Mr Hennie Potgieter who told me the salesman had resigned and that hd will fix it and order thd stickers, he decided to order **** ones as well and has promised to send via courier it's been weeks he keeps on telling me stories and when I ask why is he not ordering the original jst like the other opel grandland he said it was expensive about R4000 rands. I wanna know who's fault is it that the sticker fell while the car was still at the dealership and why did they lie and promised to fix knowing very well they were making a fool out of me, it's been a year since I bought the car but the matter is still unresolved. I regret doing business with AUDI Mbombela
