02 call me
@Jay4 This isn't customer services so no one will call you.
See ways to contact O2 here https://community.o2.co.uk/t5/Welcome-News/How-to-find-help-amp-contact-O2-A-Guide/m-p/1201413#M2924...
Also try manually connecting to a different network or get live chat to check for any roaming bars on your account.
