I don't believe that at all. They are going to piss off a customer by shutting off a reciever that they already installed and the person is paying for. That would be the dumbest thing I have ever heard.
Then you haven't been paying attention. Chuck doesn't care 9/10 times when giving the customer what they want breaks a company business rule. He's more likely to enforce the rule, and audit doesn't even struggle with that dilemma, they'll flip off the extra tuners EVERY time the account is in violation.
And before you think of threatening a disconnection, some of the disconnects of people trying to get free upgrades, come from situations exactly like this. They can shut off your account if you "ask" (read as threaten to cancel so you can get what you want.) Technically, they're legally obligated to, but that's a seperate issue.
I don't see why it's a difficult concept. Chuck isn't willing to chance more than $1000.00 maximum per customer in leased equipment. If a CSR is stupid enough to go over that, he just brings the equipment back (or else.)
It's only a matter of time until audit finds that account, and you won't enjoy that call. Every retailer should know this (CSR too for that matter,) customers still ask daily though. The days of car lot bargaining with CSRs and DISH over the phone are coming to an end.
