Who owns this phone number?

Got a call - no one on there when I answered.

Called 8:25am Central time.  I was not able to pick up the call.  Person or company left no message

Received call again this morning. The person was explaining that he works for some type of medical company that offers state of the art medical equipment for home use (some type of thermometers).  He then explained how the company is trading for about $10 a share but they are offering opportunity for savy investors to purchase shares at a discount.  When he asked what type of investing I am currently doing, I said nothing at the moment.  He then said sorry to hear that.  I tried to ask for the name of the company again because I did not remember hearing him tell me the name but he had already hung up the phone.
How rude!

Name of the company is Sano Medical.  Person asked me if I was interested in purchasing shares of their company before they become listed on NASDAC exchange.
The person was easier to talk to today than yesterday.  :)

Some belligerent guy calls daily - won't identify themselves. Now I just let it ring. Reported it to FTC.

We receive calls multiple times a day asking for my boss.  When I do not put call through they threaten me with my job saying when my boss hears how rude and uncooperative etc.  If they only - I am the boss and I am how they are trying to reach.....

Calls once a day, won't answer any questions, now just seems to call to bother us...

Rude, obnoxious guys who calls several times a day - won't identify company.

This person calls and will not identify himself and is rude and hangs up.  We get calls about five times a day from this number.  The caller won't identify his company.
