Let me also add that Dish has multiple call centers throughout the United States and so on. A good tip..... If you call and the CSR you're talking too doesn't seem to want to go that extra mile for your service, HANG UP and call again. I know that sounds like a pain in the rear (cause it is), but sometimes its worth it. Every CSR is different and they will each go to different lengths. Some CSR's will not do a thing for you, some will do whatever it takes.
All in all, you should have just signed the extended customer agreement

- Lets be honest, nothing is free. Its not too late to call back and try to work out a deal for coming back. Either way, good luck.
EDIT: This is still an upgrade, which warrants an extended user agreement.
As for the tripod installation costing money.... never heard of that (at least not here).
