Hi @pashby, that was almost certainly a scam call as Openreach wouldn't ever call a customer out of the blue to take about cutting someone off. If you wouldn't mind reporting the scam call on this link it will help us fight the scammers.
Thanks! I reported both calls I received this morning. After asking them numerous questions, I did ask them , quite seriously, if they wanted to hack my computer or scam my bank. Amazingly, they hung up.
