I got a message claiming something about tax fraud and being arrested. I called back and a women answered with an accent, asked if my phone number was the number called and wanted me to give her my name. I said you called me, I'm not comfortable giving you my personal information over the phone. Her response was calm down ma'am and hung up.
I wonder if it is a coincidence that I receive no robo-calls until I log on to the internet? Anyway, this "Unavailable" caller calls around lunch time every few days, never leaves a message when voice-mail picks up (which doesn't identify name or number).
I received a message from this number regarding tax fraud. Said if I did not respond I will be arrested. Know its BS. IRS does not make phone calls to individuals. Contacted IRS about previous calls received. Was told they do everything by mail. It is all a SCAM. They need to be arrested.
