Auto Baltic Midrand has Worst After Care Service, please be careful

I purchased brand new Volvo V40 T4 for my wife in 2014, and the car had all sorts of technical problems. Instead of replacing car, Auto Baltic Midrand waited for car to be out of Motorola before they could tell me there is nothing they could do. Driven by family protection, I replaced the car with another demo Volvo in 2017. Recently my wife took the car in with engine warning sign. After 2 weeks of holding the car, the service manager and his assistance called me in, to tell me the problem was water in the petrol tank, and motor plan does not cover such...R12 000 invoice with R9 000 being labour, when it costs only R2000 to clean tank external service provider. Strange enough, all my cars fills up at same filling stations, and never had this problem. I had similar problem with my previous Volvo from same dealership.
