Good evening @AESHJ,

Welcome to the O² Community!

Can you look at your invoice and see exactly what it says? Maybe also make a screenshot of it, of course, make the important customer data unrecognizable. Because under Connections & Services are some services listed.

Here in the forum it takes about xx-14 days until a moderator answers.

If this takes too long for you, you can alternatively call customer service at: +49 381 38 37 98 79 or you can write to the customer service via live chat: O2 Livechat (We are here for you from Mon. - Fri. 8 a.m. - 8 p.m. and Sat. 10 a.m. - 6 p.m.)

Hello @AESHJ, great to have you in our Community

@RhobarDerIII has correctly pointed out that it will help a great deal, if you can provide us with the payment details from your itemized bill (Einzelverbindungsnachweis). If activated, you will find it in Mein o2 under Rechnungen Einzelverbindungen.

You can post a screenshot here, of course with personal data anonymized (for example: your phone numer, customer number, full name should never appear on the forum)

If by any chance you have found the solution already, let us know what it was in the end

Best wishes,
Rebecca
