I have the 250 package but I pay for it on an annual basis and thus it doesn't show up on my bill and I pay for the locals separately.
I know when I originally got my 622 that I agreed to pay a monthly lease fee but I don't remember agreeing to let them raise it and it sounds like they shouldn't be charging me anyway.
Taz, I'm sorta in the same boat as you, I've leased a single 622 since around July 2006, I had been paying the $7 lease fee monthly (think it was $6 originally). I asked cust service several times "why am I paying a lease fee when this is the only rec on the acct?", their response was "at the time you leased the 622, there was a monthly lease charge, even if it's the only rec on the acct". I figger they'd gotten their moneys worth outta me (plus the $199 lease upgrade fee

that I paid upfront), in January of 2009 I emailed the the "ceo at echostar" (executive resolution), here's what they did for me.
They sent me another 622, I sent the 622 back I was using (at the time) and for a period of 12 months I wouldn't be charged the lease fee. (Yeah, it sounded crazy to me, too, having to do that but I thought, "I'll save $84 for a year), after the 12 months was up I'd have to do another swap out or if I upgraded my rec to a 722, then I wouldn't have the lease fee. I didn't wanna spend the $75 upgrade fee for the 722 and start another 24 mo contract. I've just gotten the bill for my 13th month and they haven't started charging me the lease fee so I'm hoping it's history.
It looks like they're charging you and then crediting the charge for the lease fee so as long as this is the case you aren't paying the lease fee (another Dish convoluted way of billing/accounting).
I have the Absolute pack w/locals and dvr fee.
