Worst place to buy a vehicle

We buy Cars Epping branch collected my vehicle over a month ago and still no service from them. I canceled the sale due to a inferior product was sold to me and now the want to use tactics that is "not according to the consumers act" valid. I am in the process of handing them over to the motor industry ombudsman and my legal team. Do not buy a vehicle from We buy Cars. The will do you in.
