Thanks gg, so the scam had been recorded and not answered live. I clicked on 1 so no problem?
You were only responding to the 1571 service (click 1 to hear the message, 2 to save or 3 to delete) - nothing will apply to the actual context of the scam message.
Yet another one (obviously they have my number and keep trying). 01789633629 - reported and blocked.
Third one of these calls for me. Different number 01705 568536. Now reported and blocked.
Yet another one. This one was automated. Actually sounded robotic! From 01284770726
If you respond, then they know there is a real person on the end, and will add you to a "suckers" list, and you will get even more calls, so just hang up and do not speak, or press any buttons.
They will also try to extract personal information from you.
Nothing to do with BT.
Sometimes these callers use non-existent area codes. You would think that BT could add an option to their Call Protect service to automatically block such "impossible" calls!
