If you're paying for a service call you should not have to sign a commitment extension. If you would have waited until contacted it would likely have been free with no additional commitment.
I wonder if you indeed have to wait to be contacted first or can you get the re-point deal by calling in? Atlanta is a huge market and they have not put out any letters in this market as far as I am aware, yet a ton of customers in this area have mixed arc setups and are no getting all the Hd channels right now.
