It depends on the stores communications to the Networks via the TopUp Services, it can be instant, it can be a good while...
You can always 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 or call 4445 and see if they can see any issues.
