I have to say that I have not had any billing issues yet. Even Got the TV for subscribing in a very timely manor. The install tech showed up on time and completed the order very professionally. Never an issue.
However, I do not know why it takes an order to come to completion so long. Recently, I ordered the three month free HBO/ CINIMAX package. Ordered it on Thursday, and it took until Monday for it to show up!. In all of the years that I had Cox Cable, the order was usually complete before I got off of the computer or the phone. Instant. Why it takes four days in this day of automation I do not understand.
