Just called me,didn't answer and no voicemail left.

I just received a call from this # and I answered. They caller never connected or said anything. After a few seconds I hung up.

Constantly getting calls from this number, 251-206-7197 and 305-209-9944 several times a day everyday. Nobody leaves a message, I am sick of it. I re-registered on the DNC list but don't have faith in that system.  I just hit the hang up button and move on but it is starting to grate on my nerves. I wish this old Blackberry had a # blocking device but its' a free work phone so I deal with it.  Here's a hint to you telemarketers if we don't answer your calls and you don't leave a message we will never answer your calls. Stop wasting your and our time. Thank you.

They called me today about home security systems, told them to F5 me.

Definitely a scam. Same company that has called me for weeks now. I have repeatedly asked to be put on the DNC list. It doesn't work. These jerks need to be locked up.
