We Buy Cars Brackenfell fails on service delivery

I bought a vehicle there last month and have had endless problems. I have emailed them my complaint at Brackenfell branch where I bought it and phoned them as well. All I got was an email with a reference number at the beginning of the week Ref 168913. I phoned in and said I wanted to speak to someone urgently as they ignoring my email and was told I couldn't speak to someone as they will escalate the call and get Nomfundo to contact me as she was dealing with this matter. I am still waiting. Their follow up service is ridiculous...I paid cash for the car...had I owed them money I suppose I would have had endless calls by now. I have had no use of this vehicle and had to go back to forking out R6000 per month for Uber. It has been a financial strain and that's why I thought to invest in a car as it would be cheaper. I'm also paying insurance for a car that I don't have. I need urgent assistance in this regard The vehicle is an Opel Adam 1.0Turbo JAM
