Everyone knows this forum is always the last but the best option if you have any issue with NZ mobile or broadband provider.

I requested to bring my slingshot mobile number to vodafone. I tried to do it online yesterday, but it was unsuccessful.  I rang vf this morning, the lady grabbed all my details and tried and failed. She asked me to ring slingshot to get advise. I called them and was told that I could use either sim number or my slingshot account number when do request. I used both through vodafone website, failed , failed again. Then I did ring vf again, the lady tried and said it's on process now. Then I went back to my online account to check the status, it shows"

Initial checks indicate that the selected service provider may be incorrect and your request has not been sent to the selected provider for validation. Please check the details and resubmit the request."

The message is absolutely as same as what I have seen a few times before.

It's quite frustrated just for the number porting. 

Can anyone help?
