Assuming this call, and others,are just playing recorded messages, the thing to do, when a phone call comes from a number you do not recognise, is to pick the phone up and say nothing. If it is a scam call after 5-10 secs, you will hear a a very quiet click. It is definitely a scam and the tape machine has automatically turned off and moved on.
I did do this once on a genuine call and after a few seconds someone spoke the other end and I just apologised and explained my silence.
The advantage of this system is I have no idea who pretended to ring me whether Amazon, Microsoft, HMRC, or Uncle Tom Cobbly and all so do not worry about it.
