800-536-9445

This number calls me at least twice a day. I have told them 3 days in a row to stop calling me and so far they haven't listened. The next call I am reporting them.

This number calls me 2-3 times a day.  I don't pick up and they never leave a message.  They were calling my cell phone as well but I was able to block that one.  
so far just today they have called 9:11 am, then 1:01 pm

Calls me 3 times a day. No one there when I pick up. Incredibly annoying

Yes it is someone trying to sell insurance. I tried to get a quote online a few weeks ago, and they have been calling me multiple times a day. Sometimes they call me 3-4 times in the span of a couple minutes.

i am receiving calls from this number as well...no message ever left and no one when I answer.

I am tempted to pay for Ooma prime membership just to get the block calls feature.  These people are relentless.  They call several times a day at different times.  
The caller id say either Toll Free number, Anonomys, or nothing--the number is always the same 8005369445
This has been going on for a month or so.

Get about ,two to three calls a day, but my phone doesn't ring.

Why?  If you have a Android phone you can get the Call Control application which allows you to have a  unlimited black list.  The best part is that when others report a Scam or Telemarketer number, if you choose it can also be automatically blocked on your phone.
Every time you report a number it goes in the database and the helps protect others from the relentless calling of scam artists (like NAM Marketing) or Telemarketers.
If you have a iPhone... sorry it does not work.
