My O2 Rechnung

Hello, I have a mobile SIM contract. My latest bill is unexpectedly high due to third-party charges ('Drittanbieter') that I never authorized or signed up for. Could an O2 moderator please look into this, block the subscription permanently, and arrange a refund for these unauthorized charges? Thank you!"

The contact details of the third party provider should be in the invoice. You should contact them directly to request termination and a refund. You should also set up a 3rd party block on your account. This can be done in the app or the customer portal.

Hello ​@Betty02,

welcome to our o2 Community 🙂

That is quite a shock when your bill is so high.

Could you already check for the details of the third party charges in your bill?

Best Regards,

Gerrit
