How do I actually transfer my number over

[IanWarsett]

I’ve just returned to O2 but this Amy not last long as customer services help is poor. I am trying to transfer my number and add my account to an existing my o2 account as I have other rohien used by my daughter.
Keep ringing 202 and it cuts you off and refers to my O2 which just goes round and round and doesn’t help. How do I do this.
If I can’t get an answer shaarpish the new phone is going back.
