Joined 2 Degrees today.

Im trying to add the $19 combo pack but I keep getting an "error" text message saying;

"Sorry we can't understand your txt. Packs are '10txt', 'Every100'...etc"

Problem is that the $19 combo isnt on that list.

Ive tried from the 2Degrees website as well as the SMS short code.

Has anyone actually added this pack successfully?

Thanks
