O2 Billing Issues

Hi there,

In June 2021 I started a contract which included M250 fibre broadband and a 5GB Oomph SIM, I chose to take the offer with the SIM as it ended up being cheaper at the time than to not take the SIM. I never used or activated that SIM.

With the recent O2 merger, I received a new SIM which I also didn't activate or use, I promptly put it somewhere (potentially even threw away because I didn't think I would need it). A while back I received a bill and a notice of disconnection from O2, at the time I assumed it was a scam because I forgot about the merger.

I've tried to call O2 to pay my bill, but they won't let me (more precisely, they won't tell me how much I owe) because I don't know the phone number associated to the SIM and I can't provide any other details relevant to the SIM (failed security). For similar reasons, I cannot pair my VM and O2 accounts, or set up an O2 community account to post in their forums.

Interestingly, the second and final physical bill I received from O2 was in November 2023 - besides that I've got all the necessary info such as account numbers, billing numbers etc, just no phone number!

If someone could assist it would be greatly appreciated!
