You've not given us much to go on there.....
If it's PAYG you need to top up Guide How to Top Up (PAYG)
Otherwise, contact O2.
We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) , they should be able to help you with this
Thanks
