I recently cancelled my monthly payment plan with O2 because I’m moving abroad. I went to the O2 store in Maidstone, where they cancelled my contract and informed me that my final bill would need to be paid through the O2 app, just like previous bills. However, my SIM card was disconnected on the day of my flight, and now the app won’t work because my card is no longer active.
When I tried to pay my last bill, the app showed an error. After looking online, I found that the app doesn’t work once the SIM is deactivated. I’ve emailed O2’s complaint support multiple times for help but haven't received a response. Since I’m now abroad, I can't call their support team either.
I also attempted to log in to the website to pay the bill, but they send a verification code to my disconnected number, which prevents me from accessing my account. I’m unsure how to proceed and would appreciate assistance in paying my final bill.
