Woohoo finally got my plague today!!!! Number 1341.
I had my letter about 5 months ago and had called chasing them up but what seems to have pushed it through is that one of those independant survey companies called me a couple of months ago asking what my experience with VW had been and I let them know I was not happy with the way I was being treated in relation to the plague. Then a week and a half ago a woman from VW called to say that they had recieved my negative feedback and that she was going to to get it sorted for me and that I should get it within a week.
Quite pleased to get the number for the car but I am away to trade it in now anyway!!!
