Ever since FB put the required Messenger app on peoples pages and required them to download it to get their messages, I have been getting these calls about 2-1/2 weeks ago. Here's a bunch more that are showing up. When you mention it on FB everyone thinks it's BS. But if you read the fine print, they can take all of the person's contacts and use them at their discretion. Be prepared, because the people who have downloaded the app do not realize the problems it is causing those people who do not even use FB.
