Got a call from this number on my cell and a voicemail was left offering me a good rate on health insurance. Call blocking app tagged the call as being "health insurance" as well.
They are scammers. All they want is your personal information and credit card. There is no marketing. no company, just a scam. Has been operating for a while now.
Don't bother responding, or blocking or asking to be taken off the list. Just ignore the call and warn others. Any robo telemarketing call is illegal. Warn the elderly and the gullible.
