we buy cars in midstream

I’m having a problem with we buy cars in midstream were I bought my car

A Audi a3 2.0 fsi and after about a month and a half the car broke down with meager gearbox problems

the car only have a 121000 km on the odometer wen I bought it and is now on 123000km

And its not reason bill to expect me to carry the cost of the repairs as I bought the car for R78000-00 cash and was not told of any problems and as I only been driving it for 53 day

I don't expect them to fix the car at Audi dealership I'm willing to get the car fixed with a second hand gearbox

I will like to keep my car just want it fixed I have contacted we buy cars and thy responded this
