CenturyLink Scammed by Rep by Adding a service Nationwide

I dropped our home telephone service with Centurylink and retained them as our ISP.  I get a letter 2 weeks later stating that I signed up for Centurylink@Ease.   Confused, I researched it and found out that this service costs $9.99 per month. Huh? I NEVER authirized this and called to cancel.  The letter stating that I added this serivce Does NOT list the cost - it is very low handed and purposely confusing.  Unsuspecting consumers will think that this notice is a general part of the internet serivce.  With no costs listed, many will not even think about it.    

I am filing a complaint with my BBB.
