Receiving bills even when my contract with O2 has ended

[Wrong_billing]

My contract with O2 ended in June 2024 and I have left the UK, but they still sent around half my normal monthly bill. Why is this? Has anyone been in this mess before? How did you resolve it? I have no access to UK line anymore and I cannot call O2 customer service. The virtual agent is referring me to O2 App which I do not have. Can someone drop a working email for O2 customer service?

Did you actually cancel when your contract ended?
