Constantly calling me, non stop, with no message.

I just received a call from this number.  Caller ID said "Cellphone Florida".  I answered and had silence on the line.

Got this number twice today, answered the second time and it is a company trying to sell a home alarm system. When I told him we rented, he said we do not fit their target demographic but we did qualify for an unsold Caribbean Cruise Line cab...click...

This number, 813-445-8288 keeps calling and calling and calling. No message is ever left. I decided to call this number to see who or what company would pick up but the first time only received first no sound at all, then a sound like a vacuum. The second call I made only received a recording that stated my call did not go through. This is a non sense number calling for sure...perhaps a scam from India.

Well, what do you know? THey called again...(I just posted that last comment about my belief that it is a nonsense number calling. I picked up this time but didn't say anything. An automated voice simply said, "goodbye". THese calls need to stop.
