Dish False advertising Dallas Nationwide

My husband and I have been with this company since 2013 And when we signed up for service we told them we had HD tv's They responded by saying the did not offer HD dvr's and we could not qualify right then for the hooper. They then told us that after 2 years of good payment history and service we would be able to upgrade to the hooper they offer. So Monday we got a friendly post card from them that said we could up grade no money up front. So I called this week and they then told me oh we are sorry but you have to pay $350 for the hooper or $250 for the new HD DVR. I mean seriously they lied to get our business then when I pointed that to the Rep she said she was sorry but that there was a chang in policy. I am sorry but this company should have to honor what they told us and their other customer's.
