I REGRET DOING BUSINESS WITH AUTOHAUS BEYERS

I bought a vehicle about a year ago and they are refusing to register it in my name I’ve been begging them now they have become very rude telling me it’s not their problem I constantly have to buy permits because I need to use the vehicle. I’m scared sometimes to even use it thinking that someone will come and claim it as theirs. I have run out of options they are not budging 😭 someone please hook me up with an ombudsman or a lawyer or someone that can help me 😭😭
