Call Received 10/22 at 5:53 PM.  Did not answer and no message left.

This number calls my phone all day.  I have no idea who or what they are.  I call back it doesnt even ring.  I get a message saying its not a valid extension.  I am tired of this number calling my phone.

They call several times a day. At first, there was nobody there, but I could hear the sounds of a call center in the background. Now a computer just says "goodbye."

Do not call me anymore!

Try to call back no answera9r7

I have 5 lines and they call on all lines. Nobody is there. This goes on all day for the past week. Apparently no brain cells at that number. All I do now is just hangup.

This number continues to call my cell phone and I am finding it distracting and manipulative. It is as invasive as spam and pop-ups which are encouraged by these websites.

They told me that I request info on some green thing and I told the guy I never heard of them so he just hung up on me. Since then that number has been calling every 30 mins and when I answer they don't say anything. When I called them back to tell them they didn't have to call every 30 mins, I was told that was a nonexisting ext.

Same as the other people posting about this no ext you can't call back

calls several times a day. i try to call back and it says not a valid exchange
