I think this might be the same number that kept calling me a few months ago about "pills". I've called them 2 times today right after the call and got the voice mail - left the message that I would report their harrassment if they called again. I'm hoping that works. If anyone has other suggestions, they would be most appreciated.
I have filed a complaint with the national DO NOT CALL registry. This company calls my phone every day. You can register your home phone and mobile phone with this service and they DO take action. Google "DO NOT CALL REGISTRY", or go to the Website: www.donotcall.gov.
I too have received calls from this number with no one speaking on the other end. Called it back and left a message not to call again or I will report it.
