Being billed $17.99mo for Netflix EVEN THOUGH I pay for Netflix directly for their service!!!! Anyone else???

Recvd. my bill today and under "Other Service Providers" discovered a charge of $17.99 for Netflix. Thought this was odd since I subscribe and pay Netflix directly. After a lengthy Chat online I was credited but they would not disclose how long this had been going on. I would suggest that everyone check your bill!! Can't believe they have been billing me for a service I already pay for!!!
