VERY BAD SERVICE FROM NISSAN

I bought a second hand car from Nissan,in Gauteng,I live in Limpopo,Nissan kept the car for a week to fix all that needed to be fix and as per the contract would deliver my car to my house in Phalaorwa,just to get a call we need to help Nissan and get the car in Lydenburg then it changed Origstad, we would be refunded.NOT!! i 2 months now and no refund.,a mail from the Manger stating that thy wont refund me as thy request the delivery cost cash from the client if it was not added to my finance fees.AND then I received the car with NO repairs done !! The registration papers I only received a month later. Till today not one thing on the car has been fixed,Even the spare keys I had to ask for with a replay \OO hy le hier in my laai was op n tyd weg
