I sent my broken 722K back last week. When I took it the the FedX store, they gave me a receipt with a tracking number, which I checked and it shows delivered date. Also, I got an email from Dish when they received it. Also, my online Dish account shows that it was received. WHERE DID YOU GO WRONG.!
I had a receipt and an email from Dish, saying it was received, but my Dish Account didn't show it, and I was being charged for unreturned receiver. Contacted MaryB with the Dirt team and she got it straightened out quickly.
