I upgraded to Dish Network's HD receivers and service back in december 2010/january 2011. I ordered the HD service from Dish Network Rep over the phone. They sent out a local installer to install a new dish and receivers. When the installers came, they said I can return my old boxes to Dish Network and receive a $10 credit for each box. I did own my dish and receivers. I called the Dish Network help line and they said they would send me the return boxes with labels on it to send it to them. I was told it would take up to 60 days to receive the credit. I was told this by both the Dish Network Rep over the phone as well as from the local installer. However, after 60 days, I have not received the credit. Now when I talk to customer support, they say they have never had that deal and don't owe me anything! What can I do about this? If I wasn't getting a credit, I would've just kept the boxes. I have been a customer for 4 years.
