Recorded commercial offering work from home type scam. They provide no means of removing your number from their database. When you block their number, they call back under a new similar number. Block that one, and they call again with a new number.
I have received 7 calls from this number last week. I told him not to call me that contains call me send me the formation point I bet it's placed. I passed. In the future. Be telling them to take you off the list to get hostile towards you. Report them
This place calls from multiple numbers and seems like when I block one they change it. Screaming and cussing at them does not work either. Neither does threats of filing a complaint against them. I don't answer anymore and just swipe the phone to shut it off. Pisses me off though, and admittedly when I am at home I might pick it up and scream at them just for fun.
Check with your phone, and phone service service provider to see if blocking is offered, if not, many separate blocking devices are offered, which you can purchase. Make sure that the one you get has the ability to block entire area codes, in addition to single numbers.
