It's some dumb pre-recorded multi-level marketing spiel. They called my voicemail twice in 5 minutes. I hung up before listening to what MLM company it is.
I have been receiving numerous phone messages in the last few weeks from a guy by the name of Karl Jacobsen, this is the name in the caller ID, sometimes it doesn't show a name though, and he gives another number to call if you're interested in finding out about his program. I googled him and I think he has some type of travel program, but I saw some scam info about him, whether or not it is true, I cannot say.
