I receive several (three or more) scammer calls, insurance offers, credit card monitoring services, security services, unknown callers, etc., every day. They come in mostly on my home number but those coming to my cell number seem to be increasing. Those are mostly unknown callers, no number so you can't block them.
Googling the numbers sometimes confirms they are spam calls, some are calls from clone numbers. I have even received a call at my home number, from my home number. How do they do that?
Anyway, it is all very irritating, but I know what to expect next. As we enter the political campaign season the political robo recorded calls will soon begin. Be forewarned, I don't care what party you are from, you will start losing points with me as soon as I receive the second call. You might lose points on the first call if it comes during a nap (I'm old) or during dinner.
Be careful with the use of all the technology - sometimes it just turns people off.
