I am so upset with Dish Network I don't know what to do. I been with Dish for only two month and they will not let me upgrade my receiver to HD 811. They said I have to wait unit my current contract is up(9 month from now). I never came across a company that will not allow a person to UPGRADE their system. Can you believe this, they offer the 811 HD receiver for free to new members upon sign up. Is this a common practice not to let a customer upgrade?
