They are definitely AI.

I asked one of them if he was AI and he told me he was new so was using a script.

They respond to expected replies so if you say something they aren't expecting they carry on talking.

Yes.
I have had them.
Last time I took the phone off the hook and walked away.

I haven't had this on my mobile, ever.

Never had one, but we’re mobile only.

We have had loads. Yes they are AI.

Yes, we've had a few.

I put the phone down.

We have had loads of them used to be with BT and had thier call guardian but now with cable there is no way of stopping them . I block the number every time but they just use another number. I complained to the telephone preference service but they said without a fixed number they are powerless.

We used to have”Jo” call, now it’s David. I just say we rent and have no money. Call ends quickly.

I had a few of these calls in a short space of time on the landline around 4 or 5 years ago and treated them the same way I treat all spam calls. Nothing recently and nothing on the mobile.

Just ignore the call then look up the number where it will tell if it’s a scam number.
If it’s not, call the number.
Remember: the more you answer these people they know the number is live and will keep wringing.
