Charged twice for airtime bill

[MBxx__]

I have been charged twice for the airtime bill. But they are different amounts causing my overall bill to be much higher than it should. I'm new to o2 and not sure why this is

Guide: How does O2 Refresh work? - is one a Device Plan and one an Airtime bill, @MBxx__?

If not, then contact O2 on 202 at around 08:10am, as nobody here can access your account. Or try using Social Media to contact O2 via the link just below. Good luck!
