Number not on account

[Confuciousmobil]

I thought I did not have an O2 account and cancelled my DD.

i have found an email saying I do have a contract with them but, when I log on to my account it is not there. Having no access to this number I can not add it and I can’t contact O2 to set up a new DD

how can I contact O2 without an O2 SIM?
