Third party contracts are very much legal, we had a customer that tried the same thing, cancelled 4 months in, we got charged back
we charged him a cancellation fee (which by the way still didn't recoop the money we were out on him),
or course he was not under contract with Dish, so they didn't do anything
he filed with BBB, and argued the charges with the credit card company,
we took him to small claims court, and not only won the claim, got the money as stated on the contract, but he also ended up paying for legal and court costs.
lesson of the story, deal with a reputable company, and only sign something if you have read and understand the terms....
o, and just a side note, we now will only do 12, or 24 month commitments, we explain that when people call, that the ad clearly says, NO DISH NETWORK Commitment, but that there will be a commitment with the installing company...
the guy that we charged back knew that from the beginning, but since we are a small company, he thought he could get around it
