The universe is telling you that there are entities hovering in wait for some of the less enlightened to provide them with ungotten gains. To summarize - ignore these [***].
It is never a good idea to call these numbers back. I always follow the rule " If it was important or someone I knew or an emergency, they would leave a message. Anything other then that ignore the call and block it. Remember, "Curiosity killed Cat"...once you call the number ten they know that they have a legit number....then the fun begins....trouble.
"Curiousity killed the cat, but satisfaction brought it back." People only seem to know half of the expression, and use it to mean the opposite of what it really means.
That being said, getting no message calls from the jerks at this number too. :)
