@madasaf1sh ..even with more context, I doubt we can help them....
@G-lynch2 your best option is to contact them, try the social media links :
You can 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 further..
