extremely bad service from VW Glen,

Vehicle had full service history. Vehicle was taken to VW for service. 30km after service vehicle break down. VW Glen charges R8000 to assess the problem. The feedback initially was Oil starvation. When we query why was there no oil, the response <br> changed to water in the fuel. The vehicle is there over two months, spoke to Roy the dealer principle, still waiting for a response 2 months later, send emails to Kevin Gillmer,no response to my emails to date. Spoke to VWSA, they say that I should sort it out with the dealership. The damage is R160 000.00, which VW Glen does not want to take accountability for there negligence. I sent the photos off the damaged part to two professionals and the response was oil starvation. VW Glen either put to little oil or no oil at all. My son has been without a vehicle for over 2 months. Is this he poor services and lack of responsibility that clients have to deal with from VW as a brand. I am still trying to understand what the role of VW SA is if they cannot help VW clients with these kinds of shocking service and lack of accountability from VW Glen. Where to from here. If anyone else had similar issues with VW Glen respond ***
