During last weeks uplink, my 722 wasn't getting the new channels. Called dish and the CSR had me REDO, all the things I had already done. Check switch as well as soft and hard reboots. No help. He said my 722 needed to be replaced, and I said I don't think so. Told him to forget it, got patched to Tech support and asked for a rehit. All is good. Took him 2 seconds. Got an email today stating my replacement will be here in 3-5 days. WTF. The first dude sent it anyway. Here is my question. I currently have a 722 and a 522. Will dish allow me to keep the other 722 and send back the 522? If so what other charges will I pick up the the seond 722? Or do I just need to send the replacement back? Thanks in advance.
