NO HELP

We bought a Chery Tiggo on 23 June 2015, the epc light came on, vehicle was towed in and stood at princess crossing for 2 week got it back last week 14 July 2015 on 17 July it was towed in again for the same problem. The vehicle has been there the whole week, the service centre fixed the vehicle according to HQ list, today they test drive it and the car does the same. I explained to them that i do not have transport and my kids need to go to school and i must get to work they simple said they cant give me a loan car, then i was told i am not being helped because my attitude stinks. So now i will be going to an attorney, ombudsman, newspapers and carte blanch. I also have all emails that was sent back and forth.
