I ordered the Sling adapter tonight. I started Googling for the sling adapter and found the thread about this rebate. The CSR I talked to did not say anything about this rebate. What do I have to do in order to get the rebate? I am an existing customer, I have the plan right under the everything plan, and I paid with my credit card over the phone. If one of the Dish reps can let me know what I need to do, I would appreciate it much!!!
