Booking office: LD Lines Portsmouth, Continental Ferry Port, Wharf Road, Portsmouth. PO2 8QW.

Try the 0800 freephone number, may be they will put you through to reservations.  I called them when the office was closed and one of the menu options seemed to be reservations.

It is strange that the booking office is in Portsmouth but the fax number in Abingdon, Oxon.

Please report back how you got on.
