I purchased Dish DVR 501 from Amazon.com, The seller said the reciever was clear of a balance, so I called Dish to transfer my programming to the new reciever and they said that the reciever has a past due balance with the past accoutn holder in the tune of $800 so they wouldn't allow mer to use the reciever which I paid $100 for and can't get a refund because it's upto the account holder wiether i get a refund or not according to amazon but the account holder said no. So now I am out $100 and am pissed at the seller. Is there any way Dish can let me use the reciever on my account? My accont is in good standing. Any advice or suggestions? Thank you very much in advance
