Direct Tv Bait and Switch Deceptive Practices Greenwood Village , Colorado

I live in Southfield, MI. In May 2010 I called Direct tv to switch from Dish Network because of a promotional brochure advertising $29 monthly, 3 months of HBO & Showtime, 1 DVR and a visa gift card for switching service that was sent to me. I spoke with a rep who told me "No Problem" we can match the service and give you $150 visa for switching service. I advised I was paying $24.99 monthly for basic service with HBO & Showtime with 4 DVR boxes. They asked for my credit card for a one time billing. In good faith I gave it to them. They didn't show when they were suppose to. When they did they spoke with my 17 year old and had him let them in. When I got home, there wasn't any instructions on how to use; and I had to call to find out how to get to my local news channel. There were no DVR's in any of my rooms. I didn't have HBO or Showtime. Those were my first 2 breaches of my contract. The first two months I got a bill for $60 odd dollars. Which I called they made it impossible, I was told by a rep I had to go on line to get this "rebate" that was not disclosed to me when calling in order. When it didn't work I wanted a rep, I was told I would be charged $20 a month for the rest of my contract for getting a rep to assist me with this problem. Fast forward Ive had a couple of surgeries for a reoccurring tumor this year and its now December, I never canceled my contract; I was indisposed. Direct TV canceled my contract and WITHOUT AUTHORIZATION charged my Visa debit $600. The only reason I knew this is, I filed a Police Report on unauthorized charges that had been taken out of my account that has caused financial stress to my family because I couldnt work at this point. Now I cant pay my light or gas bill and it is winter. Is it legal for Direct TV to breach their contract and charge me in the process? I feel that this is a bait & switch tactic by their company, and a breach of promise.
