Ticketmaster campervan tickets

Hi all- received my tickets from Ticketmaster a few weeks back, but no campervan ticket. Assuming this was a mistake I rang them up- after some to-ing and fro-ing they said that they hadn't yet printed campervan tickets for anyone yet, and they would be sent out separately, but they wouldn't give a date. This seems really bizarre- I felt that they were just fobbing me off. So my question is: is it true? Have people who ordered with ticketmaster got their main tickets but not the campervan ones?
many thanks. Steve
