I got Dish too, and they are the biggest scam ever seen. You have to keep an eye on the bill by credit card billing. It will go up per the contract, and mine began like yours.
Then they suddenly liked $99 on month, called them at about 16 months into my contract and thy said that was because of Cinemax. Told them I never ordered it, they said they added it plus an increase in programming fees! Tried to tell me MY contract permited any increase in "programing" fees", as in unlimited. Asked for a copy of my contract, they could not produce it. I said BS, and credit me, they refused.
SO AMEX did an investigation and chagred them back. Then in December they tried nailed me for $129. I called, they refused to dial it back to about $58 a month with the service plan, refused again. AMEX investigated, and charged them back.
last two months were ok on billing. They are a complete scam, just check every month to keep them honest.
