Change current o2 mobile number but remain in the same classic pay as u go tarriff

[Prabz]

I'm currently under the classic pay as you go tariff but I need to change my current o2 number by bringing in a number from another network. How do I do this? I need to talk to an o2 customer care service but there is no option for that.
