Dish Network - echostar Echostar Balance due for equipement mailed back! Littleton, Colorado

We disconnected Dish Network in March,2010,  mailed their receivers, not the dish itself, back in boxes they provided, using labels they provided.  We took our time and gas to deliver the boxes to UPS, as requested.  When we questioned what to do with the dish, we were told "throw it away, we don't want it'....we questioned "where'...no answer. WE do not want nor have a need for this dish either, so, consequently we have stored this dish now for 3 mos. and counting. Then we received a bill for $19.45, for "using their labels and boxes"???????  When we questioned this, we were told "it is a legit bill, pay it!"  We have tried talking to billing reps, supervisors, etc, finally sent a letter to Charlie Ergen CEO and Head of Dispute Resolutions of Dish Network, requesting help with this and the only reply we got was a letter from a collection agency!  We tried calling the Better Business Bureau & were told to attempt talking to higher ups in the company, no help, as there appears to be no tel. numbers to reach them.  Today, 6-26-2010, we talked with a Rep.# 4up, 866-443-5162 (direct tel. no. 720-514-8555 ext. 52271) to no avail.  He gave us the email address shown to help resolve this and hung up!  Our question, has anyone else had this problem, if so, how did you resolve it?  We do not feel this is a fair and ligit bill.
