We Buy Cars - Worst Service ever

I dont even know where to start! I bought a car from Webuycars in February. I had the vehicle for two weeks and returned it and got a refund. I then bought a vehicle through a dealership and when trying to license the vehicle, it stated another vehicle was registered to me and was unlicensed. It turned out to be the returned vehicle. I can now not license my vehicle because of this stuff up. Nobody has called me back as promised, nor responded to emails. I will be opening a case with the police as someone somewhere is driving a vehicle in my name doing who knows what. Nevermind that I am going to get fined due to not being able to renew my license disc. I am furious and this is ten months later. disgusting !
