@Brogan
As you paid a month in advance last month and you dropped to a cheaper tariff during that month, O2 have credited your account.
A minus value is a positive account balance so your bill has been paid from the credit you had and there is £15.71 carried forward as a credit for next month.
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.
