Sadly now I do not even answer the phone at all unless it is from someone in my contact list. I know this may not be the best thing for my business, but hopefully a real customer will leave a voicemail. At least 95%+ of the calls I get are spam/scam calls. We still have a home phone that is never answered with no machine on it. It only gets used to call one of our cell phones when we can't find it.
I've gotten 14 voicemails today from the same number, warning me of "too many suspicious activities on my social", and asking me to dial a number. And this after I blocked the number after the first call and vm. Seems like when you block a number the phone should disconnect the call and prevent the caller from leaving vm. Robocallers are bottom dwellers.
