A lawyer wouldn't make a difference since it's still what is written on the signed contract which is the important element as that is black and white. Everything else is just a opinion. Besides, the 72 hour cooling off period point is moot anyways as the OP said they had it for a week so even if it was available, it's already too late. There are always ways to get out of the contract even with DISH with no ETFs but it might require lots of work and also you have to hit the right people who has the authority.
