@Mattloft You probably need customer service to reactivate it for you. Below is the advice from an O2 Guru on how to get through.
Call 202 from your mobile.
When it comes to the reason you are calling, stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.

Other numbers available are here: Guide: Coronavirus Community Help and Support 

Because you're not buying anything, O2 won't consider your call important, so use the Upgrade, Lost/Stolen, or Fraud option if you have to, to get through. Otherwise you'll just be disconnected.
