Greetings O2 English speaking community!
When I try to extend my DSL contract(O2 my Home M (2020) → 50 Mbps) with an upgraded tariff (O2 my Home M → but 100 Mbps, I believe they changed the names of tariffs) , I encounter with the following problem:
clicking Mein O2 > Meine Angebote > Speziell für deine Vertragsverlängerung > Jetzt Online verlängern,
I receive the following error:
Es gibt leider Probleme mit Ihren Kundendaten.
Wir versuchen das Problem so schnell wie möglich zu beheben.
How can I “complete” my data so I can extend my contract using meinO2?
I have also seen the forum users extending contract via moderator/aid people offering help here, I am also fine with that.
Please note that my current contract runs until 6 December 2023, meaning I would be upgrading my tariff before the end of my contract.
