Because the number was local, picked it up even though we didn't recognize it. A recorded, excited woman's voice says: "Congratulations! You've been selected to win a free cruise to the Bahamas..." ... hung up at this point, blocked and reported.
Calls from this number have been coming to my land line for over 6 months. Today I received one on my cell phone. I do not answer the calls as there is no caller ID.
