Dear Sir,
I think it may be useful for your readers to be aware of phone calls I have received twice this week claiming to be Bt.
They were computer generated messages informing me that my internet connection was going to be permanently disconnected and I should press 1 to speak to a technician or 2 to disconnect the router myself.
Needless to say I did neither and hung up and contacted Bt Customer Services and they confirmed what I suspected that this was a scam.
