How to unlink two My o2 accounts?

[Polzky]

I have linked my account with my gf some time ago. Her contract ran out and is disconnected, there is only my contract in my name on the account but account details are hers and Im not able to unlink accounts or change details. Tried online chat which is pathetic and called 202 but no help here either. Any ideas if (and how) this can be done? Thanks

I think there's something in myo2 where you can tick to unlink them, @MI5 or @jonsie can confirm this

You can't.
When your contract is up for renewal you will have to take a new one and provide a different email so you get a new log in.

That's the way it is these days unfortunately. Once linked the only way is to take out a new contract,  not upgrade.
