Nobody should be intimidated to cancel any service, as long as you call them and tell them you are switching to something else and you are aware of the cancellation fees you should be good to roll. You will be transferred to an account specialist who will try to help you and see why you want to switch, at the end they will respect your opinion and cancel as you request. They will give you all your disclosures.
If you want another service, its ok. Dish is just a company like any other no need to be scared.
