Getting a call from them every couple of days.

Getting a call from them every few days, as well. Never any voicemail left.

Getting calls from this number everyday for a week, even on Sunday evening, tonight, a little after 6:30.  This time, there was a message, but all I heard was a gasp, maybe at the surprise of the answering machine kicking on before they got off.  I would say this is a spam call.

Phone rang all the way through. No voicemail left.

They just called me at 9:44PM. No messagevwas left.
