This looks like something you’d need to call O2’s customer service team about – give them a call on 202 or 0344 809 0202 or you can reach the Payment Management team on 0800 902 0217.
The opening times are:
Monday to Friday – 8am to 8pm
Saturday – 8am to 6pm
Sunday – 9am to 6pm
https://www.o2.co.uk/help/account-and-billing/payment-support
Best time to call is around 8.00am
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
