Yes, if I dial the number it tells me to go to view point research, an opinion survey company. I take it the surveys are for marketing purposes. It left part of a message this morning in a recorded female voice but the first part was garbled. My number block list is full with several hundred blocked numbers or I would block this one too.

It's a mobile device. The number is an ATT wireless number registered in Denver CO. The number is probably spoofed, as in this isn't the number the call originated from. Cindy might try complaining to ATT.

They're still at it.  No message.  ID "unavailable."    Blocked

Didn't answer, no voicemail, texted who dis?  Got enrolled in something, texted STOP, message said that I was unenrolled
