Bad service worst ever

Baught a car from them since day one had problems with the car they said they will fix the problems the first time took the car in told me no dont have equipment to fix the car then told me take the car to the oem dealer of the second hand car i baught there that oem asked me to pay went back to ben morgenrood and told them i have a maintenance warranty on the car but since i drove the car out there the first day it had problems tried to sort it with them until i went higher and told them that its unfair towards me to pay for that faults if it was drivin out there like that the first day and got told to drive for two days and see if the car is good and then any problems bring back they done 160 point check told me nothing wrong with car but i showed them fotos of the one fault that could been seen and told them in detail what is wrong and after weeks of hasle they sended it to the oem they called me to come get it and when i start the car the service light was stil on my car was dirty and nothing was done on it from August till now they are sending it away again but dont know what to do im tired of paying for something i dont drive and just dont have trust anymore in that car and in them cant believe that this is going on for so long..
