Dish Network Over charging me and changing the price for early cancelation fee's and increasing my bill Lexington Kentucky

I became a dish customer on January 4th,2015. And, I was told that I had to pay the first month of service and that was 55.76. I was trying to cancel my dish services ever since I had it cause it has been a headache and a problem. They gave me the month of February for free cause they didn't want to loose a new customer. So of course I agree but didn't know what I was getting myself into. I had to put my service on a short pause due to a situation I had at home. But, they didn't tell me that I had to ask for discounts or promotions. They, just jake my bill up. So, for this month of March I paid 57.23 and I was told that by one of the dish reps that my bill will be 57.23 for 6 months but call before my 6 months are up or my bill will go up. I was told that 2 weeks prior to that. And, now they want me to pay 158.14. I got bill for 2 months. I told them that I already paid the 57.23 and I don't have any control of the post office. So, now my bill reads 4/4/15 thru 5/3/15. I'm not keeping there service that long. I'm getting new service through TWC. But, less cheater. And, I also was told that early cancelation fee is 200.00 and now I'm hearing 400.00 and also 440.00. I made it very clear that I'm not paying that. I will pay the 200.00. But, they have threaten to put it on my account. I guess they are talking about my credit report. And, I told them we will be in court. They have not live up to there expectation but thinks everybody else suppose too.
