World Christian Broadcasting Corporation Professional looking UST bill is a total SCAM Franklin Tennessee

Received invoice from UST out of La Verne, CA for a telecom maintenance agreement.  I did not recognize the vendor, nor had my company made any inquiries regarding maintenance agreements.  When I saw that there was no physical address listed on the bill, only a post office box, I was even more suspicious.  Went to the web site listed on the bill and it looked legitimate.  However, did some more checking and discovered that many have reported receiving a bill exactly like ours.  I'm sure many have processed and paid these bills without realizing the bills were false.  It's sad.
