Leves a voice mail message as follows: "...(intentionally blurred)...if you want to know, or find out more and finally free yourself of chronic pain, or if you'd just to be removed from the list press 2 now."
These people are insurance scammers selling bogus medical devices. Please do not call them back and/or provide any personal information.
Lastly, block this number, too, if you can. However, it is one of several operating this particular scam.
If I don't know the number, I don't answer; if they leave a voicemail, I'll think about calling them back. If they don't leave a voicemail, it can't be too important. Spammers! I've gotten a call from this number (shows its out of Oregon), a call showing out of Colorado, and a call showing from the United States...all today. Didn't answer a single one, and none of them left a voicemail. Not wasting my time returning a call from someone I don't know and that can't leave a message. Some people need to learn how not to get scammed- why would you call a number back if you don't know it or they don't leave a message? At least look the number up first to see if it is from someone or a company you recognize.
