This number has been calling our home phone daily for the past few weeks.  Never leaves a message and as we do not recognize the caller ID; we do not answer

We've been getting this phone call every morning around the same time for quite awhile. They call once, and than call again about 5 minutes later. Never leaves a message, and we don't pick up if the caller ID is strange.

I am sick of this.
Someone has been calling my number here everyday and does not leave a message and as I looked this up and got this number here, I see there are others,  I want this to stop, this is annoying and something should be done about this, how stupid can they be?

I got the same came this morning... Stop it!!!

Same thing...they have been calling non-stop for several days now...never leave a message
