OpenSky Returned product and now they won't refund Internet

I bought 3 items and returned all three in the same package.  They only refunded two cause the merchant that received the package said there was not a third item (which ia a lie)  They did not explain that the label was for different merchants as I purchased everything from Opensky.  No one would help me and now I'm out $48 with no supervisor to talk to cause when you call they won't put you through to one.  I have read many reviews and this is a shotyorganization and no one should buy from these rip off artisit.
