Sprint, WTF

[krod]

So I get a phone bill from Sprint for 75 dollars... Problem is I have service thru Centurylink that is unlimited long distance. These calls were billed to me during my service Centurylink and were all on one day. They were calls that were actually made to Indiana. Centurylink states there were no malfunctions in the system and Sprint states that the calls were routed thru their system by me, i'm a commo guy, but not smart enough to intentionally route my calls thru another network. Anybody heard of this or even know if I can be billed for something if I have never signed a contract for the service?
