Sooo - it looks like somebody has put a claim into Peugeot for reimbursement for a service they never did. The source garage is in Paris, and the car came to me from Motorpoint (Burnley). And Motorpoint posted the document out to me, late.
Anybody else had this? Looks like I'll have to pay for the service, but that doesn't bother me so much as the warranty situation - I'll write to Peugeot UK to try to get them to sort it out. Any suggestions on how to get the best results from the monkey house?
So what have we learned today, Steven? Always check the documentation thoroughly before you pick up a car
