Hi @Mharcky,

welcome to the o2 community!

Usually, you can cancel any contract you have made online within the first 14 days with a form (“Widerruf”) provided in the confirmation mail of your contract.

However, I have sent you a direct message via our @o2_Support account regarding this matter; by answering it directly, you can send us some information so that we can find your contract in our data system.

Best regards,
Jan.
