What exactly does it say in your invoice on page 2/3 under amounts from the previous month?
I can't access the invoice because the website nor the app doesn't work for me for over 2 years and the customer service is so bad they don't know how to help or don't want to help at all.
Have you registered for My O2 with your phone number?
Hello @PatriciaTroha,
nice of you to get in touch here with your request.
I see that Bumer has already asked you the right question. I can only agree with that:
Did you register in advance with your phone number at www.o2online.de?
Best regards
Daniela
