Diners Pre-Authorisation phone number

[FromTheRail]

I remember finding it in a thread somewhere and will look for it and post it below if I find it, but does anyone have the Diners Pre-Authorisation number to hand?

Found it I think:

02 8225 0963

I had to go through the call centre before I found this number so gave not checked it out. Glad I've got is now as I don't want to go through that pain again.

I always go through 1300 360 060
