We had to pay - they wouldn't release the camper van until we'd paid and we needed it back because we're going away. We've spoken to the staff at the retail outlet who put us through to the boss of the service area (who, as we understand, is part owner of the company). It was the boss who has supplied the second two invoices. There's no accounts receivable as such for the service area, it's like a car mechanic really. They sell caravans too, but that's an entirely different section (and no doubt they treat the customers there very nicely )

I wondered about consumer affairs, might give them a call Monday and see what they can tell me. Thanks ladies
