BE AWARE: If you pick up on calls that are these marketing scams then you let them know that they have reached a valid phone number. They sell the numbers to other marketing scams. I now screen ALL calls. as I see it, if the call is important, then a message will be left.
I then save the number with a ZZZ-NoAnswer name, then next time they call, I will know by the look up and the ZZZ places them at the bottom of my phone list. Right now I have 64 of them.
You should also be aware that phones now-a-days are protected from loud noises and if you tick them off, they will definitely sell your number to ad agencies.
Recorded message saying "my entry won a cruise" Never entered anything like this and definitely do not give my cell number to anyone except family and friends. I always use my work number when entries, purchases and applications require a phone number. Reported it to the Do Not Call Registry.
