I purchased 2 Magnavox DTV Boxes on 10/9/08. We hooked them up that week and they worked fine. We unhooked them because we didn't need them yet and our antenna gave us the channels we needed. In the middle of January we thought we should go ahead and hook them back up since the transition was happening soon. The one box didn't work and it was used once. So I took it back to Walmart and they would return it but only give me $10 back because I used a voucher card and the voucher cards are only good for 90 days, so they couldn't transfer the discount to the new dtv box because I was past that. I didn't think that was right but Walmart couldn't do anything for me so I thought there was another way to get a box and not have to pay the addl. money we don't have. I want to give the box back that doesn't work, I just want a replacement. So is there any help you can give me? Thanks.
