Hello, I am using an o2 prepaid card for some years now and now I want to move to a contract, potentially with different provider. However, the prepaid card is registered for a different person that I don’t know and have no contact with. How can I claim the number and change the ownership? I have seen a form being posted around, however it requires the signature of a previous owner which I can’t get. What should I do? Thank you!
