I had the same problem with my 508, it took a member of the retention team to resolve it once I said I was cancealing service. Then it magically became mine once again.
Probably a good idea to remove the name and email address from your post.
All paperwork that you signed is held indefinately at a warehouse. If they need to they can have it pulled up, if it don't exist... then it don't exist.
Good advice! I always ask CSRs to verify the context of our discussion three times. In my case, it didn't work with E*.It is common for the csr's to want to add new receivers as leased when you call in. MAKE SURE you say it's purchased and verify that it shows up as purchased on their end before you hang up. Have them note the account that the receiver you are adding is purchased, may help later on.
