ROCKET COMM SVCS-EFAX & VMAIL

just found out in my ATT bill there's a $12.95 charge by this Transaction Clearing company and the item is called "ROCKET COMM SVCS-EFAX & VMAIL MTH FEE", I never heard of this company and never deal with them before, and I google the company and found that many people has been charged with this unknow services, and concluded that this is a SCAM, why the government or FCC did not get these criminals ???
