SMD have my money, van and logbook on a ****** car they sold to me

Smd is a ****, I bought a 2006 Volkswagen caddy 2 months ago, at first they delayed giving me the reg document and at the end I had to go collect it at their head office, I took the registration document to license office in Umhlanga for change of ownership, only to know the car is a ****** car. There wasn’t any comment on the vehicle that states ****** and recovered while selling the vehicle to me, I complained to them, dropped the vehicle and logbook in smd Durban and demanded a refund of all my money and money spent on the van, I have all receipts of everything I bought on the vehicle, but it’s almost one month now, they refused to pay my money and even they don’t respond to my emails, all efforts to reach their appropriate authority proved abortive. SMD will sell a car to you and if u don’t pay after 3 days they will cancel the invoice and take ur R5000 deposit but now they are making me and my family suffer on what happened to be their mistakes, I can’t even pay my rent, I can’t feed my family cos my means of livelihood is with them. Please I need Human rights and lawyers to please come to my aid and fight this people, I have 3 days to be evicted if I can’t pay my rent. I have children and I wonder where they expect me to move to, please I need help.
