Dish Network Dish charges over $100 for unreturned equipment. I returned a broken cable receiver, as I have done in the past and my account had been credited. Last Thursday I sent back another box and asked them t Englewood, Colorado

I returned a cable box that was not working. Instead of cediting my account the $100 as they have done several times before since I've been a customer, they are telling me I was never charged for this box therefore they will not credit my account. I explained to them that in the past everytime I returned one of their receivers, I was always charged and then credited the money, why not this time I spoke to several supervisors, the Executive account supervisors, they still refuse to put the credit on my account though they have the equipment, they keep sayig I was never charged for it on my account. Nor has the box been replaced.
