I’ve had a few recently, along the lines...
Ring, Ring... recorded message along the lines of... “this is BT, your connection has been compromised. Please press ‘1’ to speak to an advisor”.
Clearly, this is a tactic to avoid those of us who enjoy leading them on. Good news though, it shows that we are getting under their skin.
Even better news...
A) Feel free to press ‘1’. You will not be charged, that is an urban myth.
B) After pressing ‘1’, you seem to get connected to a ‘next level’ scammer, vs the old familiar callers reading from a script. That is, a more educated scammer who speaks good English, and who is reserved for people identified and validated as probable suckers. As such, their criminal masterminds will be paying them more and, by wasting their time, you are rendering the whole criminal enterprise all the less rewarding.
C) It is just as easy as always to wind them up. Waste their time, make them angry. And as always for me at least, the measure of success is, whilst remaining polite yourself, how much they end up swearing at you.
Above is based on recent personal experience.
