Have you noticed lately that there's an amount on your invoice that you didn't actually book? Maybe there's a subscription (Abo) displayed and you're sure you haven't taken out one?

With this little help page, we explain what you should do first.

Have you ever heard of third party blocking? If not, then take a look right here:

In principle, this would be the first step for customers: to check and, if necessary, adjust the settings of their third-party provider blocks and to block further options, such as the option of:

Subscription services

Barring of all third-party and O2 subscription services, e.g. subscriptions for ringtones, pictures, videos.

With this block, no new subscriptions can be booked/ concluded.

Possibly wrongly existing subscription

First of all, you should cancel the subscription within a period of 14 days. You can use this form and send it to the following e-mail address:

E-Mail: widerruf@cc.o2online.de

If it is a partner card with a combined benefit, you can also manage both contracts together.

Addition

Contradict the bills and ask for a refund with justification.
