I had a pansat
I bought 2 different receivers off Ebay one was totally a mess...the Other was a Pansat 250sm I think, the seller said it was in new like condition and worked but had a no return note. When it got here it did look new but when I hooked it up..blinky lights and wouldn't do anything else. Boxed it right back up and contacted the seller, he refused to take it back or refund any money. I contacted Ebay filed a complaint and contacted Pay-Pal...Needless to say after about 2 weeks I got a total refund and was told I could keep it. I returned it as it was not worth my troubles. I learned really fast not to buy a used receiver unless it is right in my hands and I can test it out first!
Really very sorry you had to go through this and hope the seller will do the right thing and refund your money. If he doesn't contact Ebay maybe they can settle it for you...
