We Buy Cars sell faulty vehicles

I bought a bakkie from We Buy Cars in Port Elizabeth. 100km from the branch on my way back to Cape Town, the indicators and wipers stopped working. I informed them the following day and didn't hear anything back. I informed the seller and he told me it's not their problem and I must take it to Ford because it's still under warranty. I've taken it to Ford three times already and am still having the same problem. After 100 emails and phone calls, they eventually phoned me and said that their DECRA report showed lost communication amd other faults(they did not tell me about this before hand and kept it out of the report). Before buying the bakkie, they told me there is nothing wrong with it and is neat car. Only had 18,000 km. If I knew that I never would have bought it. They deliberately witheld the information of the faults on the vehicle. They do not want to refund me and say I must take it to an auto electrician. I have been driving without indictaors and wipers for over a month now and no one can seem to solve the issue. We Buy Cars are ********s, and they need to be stopped. They are not trustworthy. If you read this please think twice about buying a car from them. They make it impossible to get your money back if anything goes wrong with the vehicle you sit with the headache and they just dodge your emails and phone calls
