Thanks MediaMan for info on who this is. They are blocked but have attempted 5 calls in just a day. This is harassment. It's just astonishing to me how nobody is able to stop these folks from bothering us endlessly. I too am ready to give up the landline and never tell anyone my cell phone number.
Recorded message that will answer questions like "who are you?" and "what company are you with?" after the normal hesitation to find the appropriate answer. Recording said they were the Pro Life Center or something like that. I hung up and blocked the number.
