Picture this: you come back home after a hard day of work and suddenly your phone rings
The number is not in your phone contacts but you pick it up as you know the area code
And out of nowhere a nice voice starts to speak up and starts offers a kind of business proposal
You want to slam the phone down but well your manners kick in and you want to be polite and let the person finish on the other end of the line
After a while the man on the other side of the phone asks you that if you can hear him and as soon as you answer the question he hangs up. Well congratulations a scammer just got to you
They record your voice and use it as evidence that you said yes to a product or service they were offering
