The Optus wide number share activation issue was resolved last Friday afternoon.
Perhaps if you return to the store the guy trying to assist will be able to proceed.
Otherwise if you’re still needing a hand, we recommend messaging us via the My Optus App. The team is available 24/7 and are ready to assist customers as quickly as possible.
Geez how frustrating! I'm afraid it's not something we'll be able to resolve here though.
If you have a social media account, please then send a PM to Optus on Facebook or a DM on Twitter with the details for further assistance mentioning you have an unresolved issue that the store or Messenger team cannot fix.
Please see our help and support article: Number Share - What You Need to Know
As we don't have access to customer accounts here on this public forum, you'll need to contact Optus directly for further assistance.
