My recommendation would be make sure you pay your bills, have your account in good standing for at least 6 months and request an upgrade for something you are not happy about. Be nice, be honest and ask to cancel if you are not happy. I just received free 12 mos DVR and HD service and a free HD DVR and Slimline upgrade. I truly wasn't happy about something.
Now, here is my current problem. They came to install the new dish and told me they couldn't mount it on my 2nd story tripod and the locations on my roof without the tripod resulted in no signal for the 119, therefore he wouldn't install and he wouldn't leave the HD DVR. "Supervisors" are supposed to stop by tomorrow.
My question for anyone who knows: I may really want to cancel now, especially since they won't leave the DVR and I can't get the new channels anyway. The DVRs they just sent me have some tremendous bugs, so I would like to send them back. Is there still a danger of them charging me something because they gave me a 2 yr commitment with my above deal.
