We have used an English builder working in France to assist with our renovation. We have asked for receipts and invoices since he started last summer but have received very few with various excuses given. We have asked for a facture and guarantee for a roof which was paid for in June. The builder has said he will give us these but needs us to pay the VAT on top of our original payment or he won't be able to give us the guarantee. I want to know if he can do this - add on VAT months after we've paid, and refuse to give us the guarantee if we don't pay it. This is obviously going to apply to any other paperwork we ask for. We have made a lot of errors dealing with this bloke and could kick ourselves for choosing him to do the work in the first place. Any help gratefully received.
