Left a message saying they are conducting an immunization of children survey. Says to call them back at a completely different number, or they'll try again tomorrow. I have no children in my household and wish they'd take me not answering as a sign that I don't want to talk to them.
Got a call from this number, they left a message, it was my friend who was in a mental health facility, I was unable to call back, just got a busy signal but it was not a solicitor or survey, it was definitely my friend.
Lady caller doing an immunization survey for the County of San Diego. Asked three simple questions, "do you live in the San Diego County? Any children under two living in your house? Anyone pregnant at your home?" - no sales pitch, no invasive questions in my opinion. Sounds like a legitimate call. She was also courteous at the end thanking me for my time. Still, I never pick up the phone if the area code is not mine or the number is not a familiar one.
