Got a call from them they left no message. Caller Id says GB marketing

Thanks, but I can't tell you anything since I won't call it back, erased it, and haven't got another call.   Was just checking to see if anyone had mentioned if they knew who the caller was.    I guess my new # being someone's old # might have something to do with it, but it was 800 so I'm not sure.  
Now the last "000000" number calling, I've never seen that, and doubt it's able to be recalled!

Thy called me on my cell phone at my house and they left no message

Its a sales pitch for home security.

417-800-2801 they say the FBI is reporting, ..... I hang up.. received call serveral times the last week, upsetting....

Called me at school. No message.

623 845-9048 two calls in one day 10:04pm and 9:17pm 4/18.  I have a do not solicit message recording on my phone telling solicitors to not call, am on a do not call registry and have a recorded message from the telephone co also stating that solicitors should not call.  Every time I receive a call like this I report it to the AG office of the city I live in, so I do not understand why they just do not take me off their phone list.  Cell phone contact What do you think would happen if we all called them back at the same designated date and time and see how they like it.

called back and selected 1 to talk to someone. was transferred to voice mail. I suspect telemarketing.

Just got called on cell. Did not ring very long. Would not have had time to answer even if I had wanted to.

Got a call from this number, as usual I don't answer these unknown numbers and came here, good to see I'm not the only one, probably another robocaller, spam - they left no message.

You still will have the same problems - Almost all numbers are someone's old one!

I have a new number. Found a cheaper carrier.

Jo -

Your "brand new" number is somebody else's "old number".
But, since you told us nothing about the call, we can tell you nothing about the risk involved.

Just got this call on my cell that's brand new and no one but 3 people have the new @??? - Not risking calling it back either, since it's not been identified here yet.

telemarketer

called my Google Number for my company. Did not leave a message.

Called me at work, I didn't answer. They left no message.

received a recorded call pushing their "...free alarm system..." if i allowed them to place a sign in my front yard, just like my "... local police department want me to..." yeah, i wonder if "sucker" or "here's the house with the bogus alarm system, please come rob me" is printed on those signs, too.  saddest part is that there are people naive enough to fall for this scam.
