Does anyone else have this problem?

Booked with disney uk and got UK reference number. Wont work online

I phoned and got my US booking number, STILL the online ADR system wont recognise my booking, says bad phone number

tried my phone number without the 0, nothing so phoned again and they gave me the disney UK phone number which they say is attached to all disney uk bookings

STILL the online adr system wont pull up my reservation

I know I can just phone up but what a pain ?!
