Received hang up call in voicemail.  Number blocked.

The only reason you're getting calls from this number is because you or a family member signed up online for a free book & guide from WDM, and the call is to allow you to receive your free book & guide.  Sometimes other family members, such as a spouse, signs up and the person receiving the call doesn't know what it's about.  And sometimes people fill in the wrong phone numbers on the submission form.  But WDM NEVER makes unsolicited phone calls to anyone for any reason.  You can also click a button when you get the call to opt out, or you can dial the caller ID number back and opt out on the greeting there.

Whoever is doing this crap needs to get fined. They're breaking the law. IF these [***] truly wanted to talk to me, WHY do they hang up? It's a nuisance! (BTW, i am the ONLY person using my phone number and I NEVER give out my phone number online for an e-book. So, I have never opted-in for anything!)
