Dude.. I feel your pain. SE has the worst customer service and yeah, they could remove the locks but don't look for that to happen. Don't count on help from SE because you're not going to get it.

I unfortunately have an EU account but live in the US but since SE refuses to change regions or unlock, I have to pay in GBP and jump through hoops to get EU copies of the game. Do you know how many vendors refuse to sell to the US because you're not in their region? Quite a lot of them.

If she already has a character that she doesn't want to lose, she needs a copy of the game for the correct region listed under her SE account. This also means that you will need to create a new PSN account for that region. Does is suck? Absolutely. But until SE does something about this, we have to jump through the hoops.
