I just got another call from this nbr. They call all the time. I hang up right away, but listened once to it and it is about a medical alert device for seniors. Tried calling back and the message is their mail box is full.
@Mary, dial *60 and follow the prompts to turn service on by selecting 1, then follow again to add a number by selecting 2 this is a free service and you can block up 15 calls. By the way it's is called the "star key" or "asterisk key" then 60 and hit dial. Hope that helps. I just got a call from ID Georgetown, CO. and they/it left no message. Jerks!
