Phone bill date

[Chloe07]

I have tried change when my bill comes out my bank but won’t let me change it. Currently the money comes out on the 16th of each month and I would prefer it to come out with my other bills at the start of each month

You can change it under the billing section of My O2

or

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

Use the specific Payment management number 0800 902 0217

The opening times are:
Monday to Friday – 8am to 8pm
Saturday – 8am to 6pm
Sunday – 9am to 6pm

There is not enough time for the revised date to work through all the systems before it would be due @Chloe07 

Try again just after your next bill is taken, or see if the payment management team can do something "outside the box".
