Can you help? I was just on the phone to Dish CSR to get a 612 receiver replaced. Everything was fine and a replacement shipped. I went on line to check that it was in the system and I noticed that the CSR had ordered and shipped a 722k. I called back and got a replacement 612 ordered but was told that the 722k order could not be cancelled even though it has not in fact been shipped yet. So they are sending a receiver I have no use for and have to ship straight back. The second order for a 612 is not yet showing up on the website. Please advise.
