There is really nothing that you can do until Ticketmaster activates the transfer option. My understanding is that Ticketmaster does not have customer service by phone right now so if the transfer option does not activate soon then you will have to use the contact form on the Ticketmaster web site to see if you can get them to tell you when transfer will be activated. If Ticketmaster support is not helping you then you have no option but to wait.
having this exact issue for the same concert! I found a seller on twitter who was having this issue with a previous Olivia concert. She said the tickets became available to transfer 24 hours before the event. I let the stubhub help team know this and let them know i woud be checking back with them by 8pm tonight! If ticketmaster was still not allowing me to transfer them, stubhub said we would see what other options we have from there.
@lgilmore918 I have the same conern about getting fined, which is so unfair because this isn't our fault that ticketmaster took awat the transfer option...I will check again tonight to see if the tickets become transforable and will let you know as well!
