Faulty Brand New Car

We bought a brand new Ford Figo 2 months ago and we were nicely assisted by Warren. 3 weeks later i put my car charger on the car charger connection and it was not working. I put it back in our other car and it was working. So i went back to Ford , found Warren and Jonathan outside, i explained the problem, Jonathan immediately said he knows what the problem is, he removed the dashboard cover to access the fuses/resistor and he changed one an and d in the process he broke the dashboard cover. He said he will call me back and fix it within 3 days, he took a month to fix it after i complained to Warren and the Floor Manager. I came to Ford twice in a month to have the same electrical issue fixed, on the last occasion Jonathan gave me 2 extra fuses to replace myself should same problem exist, and they were all used in a week. Last week i took car to Ford for an electrical check, i informed Warren and the Floor Manager of the continuing problem after Jonathan had said the dealership will not take responsibility of anything.The check yielded nothing, they found no problem, now we have moved from Cpt, on the 2nd Oct the other fuse burned. Now we Have no fuses and ford refused to supply.
