CSRs do stranges things.
Back in January I added a purchased 722 to my account; that's it, no other changes. What did the CSR do? They removed the AEP bundle package from my account, and added back in a separate AT250 package, and separate HBO, Cinemax, Showtime, and Starz packages. Exactly the same programming as the AEP bundle, EXCEPT now for about $20 more unbundle!
When a called to get them fix this mess up, they tried to change me a downgrade charge to "go back" to the AEP package. THIS WAS THEIR MISTAKE! After much arguing (and talking to a supervisor) they relented. Even then they screw up again by adding back in extra receiver fees for receivers I had deactivated YEARS ago and don't even own any more. It took me two months to get things all straightened out.
And by the way, when I added the 722, the CSR didn't even ask me about 129 access or additional dish installs (I already had a 1000.2). You never know what you're going to get.
