Moving to O2 and keeping number

[RRowley5]

I have just got my new O2 sim and put it in my phone but it's not using my old number, although I supplied my PAC code and old number when I ordered the sim. Do I need to do anything? Can't find any information about what to do in this situation. Tried to ring customer services and didn't get through to anyone, the automated system just said goodbye and cut the call.
