I was one of the few lucky ones who ported before Your 2Degrees was taken offline.
This morning I attempted to top up, and at the end of the process where you normally get the confirmation message, was transferred to the Call Centre instead. At the same time, I received a message saying, "Please enter correct mobile no for furthere service. Thanks, NZC"
The incorrect spelling in the message is their's.
Interesting that they haven't changed the branding on that message.
A support ticket has been opened but I suspect that because I was one of the few who ported, I may have found another quite significant bug.
