Norristown Telephone - USBI Unauthorized Charges Internet

I just noticed a charge on my account with AT&T.  I too called the number shown for USBI, and it is purportedly Norristown.  I spoke with John (Agent 1) and he said they will remove the charge.  I then called AT&T because I wanted to know HOW a company could submit charges to my account without authorization.  I was told by AT&T that the FCC allows this when a company receives either written or verbal authorization for services.  AT&T suggested I call USBI back and request a copy of the written or verbal confirmation for billing.  I did, and they gave me this e-mail address info@freecallzone.com (note it is neither USBI nor Norristown).  I was also given the address Norristown Telephone P.O. Box 1566 Blue Bell Norristown, Pa 19422.  This will continue as long as the FCC allows companys to do this.  Please write me at (((ROR redacted))) if you want to share what else (if anything else) was done to rectify this situation.
