Who called from 6192207397

They leave a message on my cell nearly every day. At least 5 times so far saying they are doing a survey on immunizations and if I have a child in the home to call them back at 866-358-2966. I don't have a child in the home so I dont call back, but they keep calling anyway. Typical San Diego County wasting tax pay money.

Repeated calls and message left. This may be a legitimate survey, but why call people who live in another county?  No good reason for repeated calls.

Who's calling from this nunber?
