after leaving O2, I could not find my final bills on My O2 online

[Leia1]

I could not view my final bills on my O2 online since I could not find any link to view my final bills. The previous one has disappeared after I transferring my number to another company.

Does anyone could send the link or tell me where to find?

Also, how to confirm that all my services has been stopped and no new bills aside from the final bills would be made?

You'll have to contact O2 to get answers to those questions, @Leia1 - all the ways are in

with the most effective probably being Instagram or Facebook, mentioned in the Social Media section of the guide.  Good luck, @Leia1.
