BIDALLIES eBay seller Sent me a DOA iPhone--wants me to pay to send it back to them. Internet

I got ripped off by BIDALLIES. I bought 2 phones on June 21, 2015. Received both but one was effectively DOA (touch screen does not respond). Filed a return claim and got no response until I emailed a warning about posting a negative feedback. They wanted me to close the claim because having it opened prevented them from issuing an RMA or a refund. Well, suckered me into closing the claim which now eBay won't reopen because "it was voluntarily closed" EVEN THOUGH I HAD CUT-AND-PASTED the text of BIDALLIES's email into the reason box.  I submitted a negative feedback and LO! and BEHOLD! a few minutes later a get an email from "Lori M" with an RMA! The problem is that I am supposed to pay to ship the DOA iPhone 5c back to them! Wait-a-minute! Did I order a DOA phone? NO, I had ordered a working phone--why should I pay return shipping when you did not send me what I ordered? Needless to say, I am out $200 and have a piece of garbage iPhone paper weight until BIDALLIES sends me a prepaid shipping label.
