Who called from 6124123727

daily calls...and today 3 calls.....no voice mail....I don't answer.....am on do not call list ....so how's this happening?
verizon wireless from Mpls area

They do not tell who they are and asking for persons name who we do not know.After that they keep calling.

I have gotten calls from this number, and countless other harassing calls from other random/bogus phone numbers. This is totally insane! How can we stop this?!

Called 2 times this evening. No message left. Location is Minnesota. No other information.
