Ebay system sucks ripping me off

Ebay rips me off again. The system is not for sellers, or buyers lately. My experience with the customer service people is terrible, no speak English broken English don't understand what your telling them. I've been ripped off only a few times, mostly lately, $225 for a Marklin Engine my credit card company Discover finally gave me my money back, NOT EBAY! Buyers don't pay for items sent? I lose. I sent a $40 Lego set to some jerkoff who claims he never received it, I believe he did just wants to claim he didn't as he didn't sign for it. I called 3 times to the Ebay contact line, wrote 5 emails asking them to look into this. Nothing, just broken English no nothings reading a fucking script???
