scam telephone call

Beware of them, on your landline and on your mobile, wherever you live.
I use the phone very little; I seldom make calls, and almost all my contact is by e-mail. On Friday, I received two phone calls, unusually. Both were scams. The morning call was from Amazon advising me there was a problem with my Prime account. My imaginary Prime account. The later call related to my ISP; I was warned of dire consequences unless I took decisive action. Both callers had robot voices, and I hung up on both.
