Miracle of miracles, I got an e-mail response from Dish Network saying that they’ve credited our account for $3.99 to make up for the pay-per-view movie that we never ordered. Interestingly, shortly after I sent my response, I checked the settings on our Dish receiver. Guess what? PPV was already locked out. So… Despite what they said in their initial response, it is possible for their system to make mistakes. But… At least they did the right thing in the end.
Moral of the story: If you know you’re right, don’t let a company stonewall you.
