Bad service from Hyundai

I bought Hyundai I20 glide form Hyundai Belleville around November 2021, after I saw it online. The car was delivered and upon arrival the passenger window switch was dis****ional, the car wouldn't start in the morning due to battery fault and up to date I haven't received the licence disc and the number plates. The permit that they gave me is expired and when I call the sales person Kent he tells me to go do the licencing and registration myself after they have charged me for it . I then complaint to mfc and they did nothing about it, I decided to stop paying for the car, they have now handed over my case to debt collection and avoided the fact that I will not pay for the car that is not road worthy and having electrical faults. I am not happy with the treatment from both mfc and Hyundai because Hyundai should make sure they deliver the promised items as indicated on contract. I want mfc and Hyundai to come fetch their car since I cannot drive the car that isn't licenced and faulty
