Constant calling I dont answer unknown numbers.. I also blocked the number.

This number called me twice in one day.  No VM either time.  I called back from a land line and there was not any identifying comments on the digital recording.  I would recommend NOT answering this at all.

I have gotten a call from this number twice.. The 1st time I didn't answer it the second time I did answer it and nobody responded when i said hello. When i Google the number it comes up as a Burlington, Ia number.

Calls and never leaves a message.

Calls quite often, leaves no message
