I have been with 02 for 25 years. My income came in late and after I paid my bill on 04/07/25 instead of 30/06/25, the O2 declined to reinstate the service. On the day I paid the bill, O2 wrote me a note claiming that my out-off-allowance spend is barred and will not be able to spend outside of my current allowance until the bill is paid whereby the bill had already been cleared.
