The caller inquired if my boss was in the building

The first time this number called, I was at work and they left a voice mail. The message is very muffled and you can't understand what they are saying. I managed to pick out the 512 phone number, but couldn't catch anything else they said. The number in the message did not match the number that came up on caller ID. Since that day, they have called several other times and not left messages. Looking online, it appears that this is a scam phone call.

Called, hung up as soon as answered, same thing with returning call.

Did not give a chance to tell what she wanted. I told them I was on the do not call list and to take me off their list and hung up. They have called a couple times a day since my 1st report. How can we stop these people.

This number comes up on the ID as 800 Service. No one responds when I answer the call.

will call 3-4 times a day. Nobody on the other line

Calling for a person NOT ME and insinuating I have done something wrong

we are on do no solicte list yet get a call from this number repeatedly.....this is a scam number
