Continue to call. It's an automated voice saying don't hang up and it's about pain medication. Extremely annoying!!! I'm on the do not call list, which obviously does not work.
The scam revolves around collecting information about you and your health insurance, so that they can send a low cost miracle pain cream. They call through from several different numbers, and may be associated with a number of other scams The phone ID can be either "customer svc" or "alert" (and who knows what else). I made up a bunch of information for them, and hung up after getting bored with it all. They do a pretty good job of sounding legitimate, although the miracle pain cream idea seems a bit idiotic. They also call through 917 818-0265, and it seems impossible to stop them from calling.
