Extremely bad response on my car inspection

I just realised that my 2013 Polo vivo which I bought as a used car at this dealership around April 2014 was over heating, on Thursday 12 November 2015. I then decided to take it back to the same vw dealer the following day, as the car is still under warrantee. After a very long wait I was then accused of damaging and repainting my car and told that my extended warrantee won't pay for my car, because something/someone (that being me) damaged the cooling system with a very negative attitude. They then told me that it would cost me R3 600 to fix it which I have to pay in cash. I then decided to seek second professional opinion and to my surprise I was told that a fuse is dead. After replace the dead fuse my car was no long overheating. <br> Now I have to take it back to them for re-inspection, so that my extended warrantee can continue. I just wonder what they'll say this time.
