They have called a millions times! Never left a message but I did pick up twice. First, there was no one there, next time a woman came on the phone asking about my electric bill. Told her I was not privy to the information and that the owners will call electrical company directly when they arrived home. Thought it would end there - they ended up calling 20 mins later. Ugh! Blocked the number & reported it.
Despite having blocked this number through my phone system, they are still calling every 20 to 30 minutes. What harassment! I have now tried blocking this number through Verizon. We shall see ...! :(
