The number is on the website that has been posted several times. You can speak with any customer service person who answers about the mailboxes and how the addressing works. As it is one of their common services, I imagine they receive calls about it fairly often.
Yup. Was a hunch. Now confirmed. The address on the ENRG site is a rented mailbox.
Energy Telecom 3501-B N. Ponce de Leon Blvd., #393 St. Augustine, FL 32084
Note the -B after 3501, which designates the UPS Store Suite. And then #393 is the mailbox within the store. They specifically market that they provide you with a "A real street address, not a P.O. Box number- providing a more professional image for your business".
If someone does run over there to try to find the company, they will be able to confirm this fact.
Of course this post is my opinion. Every post by anyone is an opinion. I'm not writing a white paper on scams… in this post, anyway...
