Ah, one last hiccup in the grand scheme of things: Since I was an annual AT120 customer, when I converted to the DishHD Silver package, I had enough credit on my account that I won't be billed for the next three months.
What's the problem with that, you ask? Well, you need to send in a billing statement showing DishHD on your account when you apply for the $100 Back Rebate. Since I converted to paperless billing oh so long ago, I would need to print out my billing statement from the on-line system. The only problem is that Dish's system is programmed to not generate an on-line statement if you do not need to pay them!
By the time I can gain access to my on-line billing statement, it will be beyond the 60 days that I have to apply for the $100 Back Offer, effectively negating this benefit of upgrading to DishHD and ViP receivers.
I have sent an e-mail to the person who followed up with me about the horrible CSR experience, so I hope that I will get this added without too much drama, but I'm halfway through the 60 days now since I had to wait for the next billing cycle.
