Car not serviced before pruchase

I bought a car that was 122 000 an was not serviced for the 120 000 km, when i tell them they are not helpful. Now this affected my cars ignition, so now I have to get it serviced which i currently don't have the funds for it. The garage is based in Gezina, Pretoria. I am very disappointed with the service as now after just 2 months I'm sitting with a car that doesn't move because of them :(
