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?

The fact you are paying less may mean the airtime is still running

My contract ended and the line was disconnected.
