I've had quite a few 'phone calls from the "SKY Technical Team" (different numbers but all originating from the area code) telling me that they've detected issues with the speed and connectivity of my broadband and want to me to do various things to help them sort it out. They are unable to provide any details of my account with SKY (I am actually with SKY broadband but of course they don't know that when they call, they just bargain on a good percentage of people being with SKY and then, with all the working from home putting a strain on bandwidth, they'll eventually stumble on someone who does have problems and then is then naive enough to do what they ask), they all speak with a strong Asian accent (SKY staff are British) and there is heavy call centre background noise. They try to prove they are from SKY by asking you to type certain commands in to your computer which brings up a number they claim is unique to your account. All in all, a very poor scam and full of holes if you have your wits about you but of course plenty of people are vulnerable to this.
Depending on my mood and how much time I have, I either string them along or pick up the 'phone and say "SKY Technical team, can I have your surname and the first line of your address please?" They hang up instantly.
