poor product. poor service

So I decided to purchase a brand new Golf 7 TSI from VW Parow in Dec 2014, barely a few months later I noticed that the roof lining was starting to mould and getting wet after a rain. I Took the car back to the dealership who had the car for almost 3 weeks running tests, yet failing to find any issue or leak. <br> I received no feedback from Lizo and would have to phone in to find out what was happening. Every day was the same story. Not sure, but running tests. Eventually got the car back after they took the roof apart and back together, and replaced the moulding lining, yet they claimed to find no leak. I asked for a report when I got the car back as to what was done. I am still waiting months <br> later.<br> Now every time I ride over a bump in the road the roof falls apart and the rooflight dangles on the wires. This after VW Parow worked on the roof.<br> After it fell out this afternoon, a passenger attempted to replace it and was shocked by the defective light.<br> I called the dealership on 14 october at 13.30 to ask to speak to the service manager. I was promised a call back. I am still waiting. This is the service you get from VW Parow if you buy into the brand?
