I'm totally fed up with DirecTV right now. I've been a customer over 10 years, not under contract. I could not get anything more than $13 a month off the Sunday ticket, no other discounts or anything. I've read people saying that they actually cancel their service and then get some offer and re-sign without ever having their service stopped. How does that work? If I tell them to cancel my service, don't they kill it right away? How far can I go with this?
