happened to me to.

they called me. They said hello twice. Little creeped out.

I receive a call from this number one a week. they does not live message. never answer

They called me yesterday and just a moment ago. I think it has something to do with collection. Debt Collectors use a number of different methods as a ruse to get your information.
Water Line Insurance
Debt Consolidation
Free Cruises
Political Surveys
...and things like Insurance Quotes. Here's how it works...
If these activities were not associated with an actual company it would be illegal. It is very easy to start a company, especially as a subsidiary or partner company. The main purpose is to get your PERSONAL INFORMATION. If they actually get you to buy the insurance or get some type of quote then they have succeeded because the main purpose for them was to get your information.
My advice...if you don't actually know the person or company calling you, don't talk to them or tie them up for a few minutes feeding them false information and asking questions or otherwise making them waste their time.

Didn't recognize number so didn't answer. No message left. My number is on "do not call" list. It's obvious some companies are very disrespectful and simply don't care about following the law.
