The FCC regulates it. They were never supposed to change your service address but some of the reps did it anyhow. You may or may not get someone next time who will do it. You can try asking for a supervisor and threatening to cancel service if they don't. They may make an exception if you say you've done it before. AT&T purchased DirecTV and may be tightening up the rules. We purchased DNS stations (east and west coast feeds) so we always have affiliate channels. It's great if you don't have a home with Directv but if you have service at a home address you can't "mirror" that service and have to purchase a separate complete package plus pay for the DNS service which gets expensive. Again this "no mirror" rule is from the FCC not DirecTV.
