To stop O2 ONLINE charges from appearing on your statement, you need to cancel your O2 subscription or account. Log in to the O2 website, go to your account settings, and cancel your subscription. If you cannot find the cancellation option or do not recognise the charge, contact your bank to dispute it and block future payments.
If you believe you have been charged incorrectly by O2, first contact their customer support to request a refund. If they are unresponsive or unhelpful, contact your bank and ask to raise a chargeback. You typically have up to 120 days from the transaction date to raise a chargeback claim. For credit card purchases over £100, you may also be protected under Section 75 of the Consumer Credit Act.
