Direct Tv Direct Tv , Rip off Newark, New Jersey

I got Direct Tv at a booth at Walmart. The gentleman said I would pay a certain amount but every month my bill was over 100.00 ,I called direct tv to straighten out my bill. They said I would get stars and the other movie channelsfor three months for free, but they charged me for them. I called them and they said that they would take them off and they did . Then the next month they charged me again for them, I called them again then they took them off. I then went back to Walmart and seen the guy who signed me up and showed him my bill which was 141 and some change. I told him I will go back to Dish Network, then his manager talked to me, I told I would like to go back to Dish. She got on her phone and texted the main company. Then they cancelled my sevice because I did not pay them,they told me that I cancelled, but I did not. They told me that my bill was over 600.00 dollars,then they told me that they would drop 420.00 off my bill. I got abill for 165.83, so I called them up to pay this months bill,then they told me that there was acharge of 40.00 dollars that I paid that too. I thought that was my bill for Oct.,but in the mail today I got a bill for 113.65 which is due 10/28/12.
