Car problems. Bidvest at Burchmore sandton

I bought a car from burchmore sandton. It was Saturday afternoon. An all the consultant were rushing to knock off that time when we do paperwork. I drove the car to the nearby engen garage an when I get there they put gazol, air pressure , water an oil and only to find there is No lid for where we put in water. I manage to put plastic so that I could drive home. While driving I could feel the car had a sound on the front wheels. An also the car couldn't reach 100km/h. This was amazing an stressing an frustrating. I had to drive 80km/h from gauteng to Limpopo. At some point they car will just stop but the engine runs. It was the first time I experience that. I drove between 60 an 80 till I get at Namkgale in phalaborwa. Then the car stopped itself at namakgale fourway at around 01h45 morning. When I put gear 1 the car moves but as soon I put gear 2,3,4 an five the car don't take those gears. I manage to get hold of my other friend we towed the car to my house. Since that day the car have been standing. The whole week I have been busy with my wife preparing for the funeral we had yesterday. So now today I'm lodging a complain. If possible you guys send a mechanic or you send a truck to come get this car an give back my money. J don't care even if you give me 70% of my money I don't need this skorokoro anymore. You guys you make us a laughing stock to people. You suppose to at least service the cars before you sell the cars. Or on the action for each car mention it's problem so that we can know. Please deal with this urgently. My email address is *** an I can also be contacted on ***
