any advice on return?

i really dont know what ebay thinks its doing by encouraging buyers to not have to bother reading listings or be responsible at all for what they are purchasing?

A buyer has bought a speaker dock and hasnt bothered to read the listing properly and make sure her tablet is compatible (321700025527).

I thought i had it pretty clearly described 4 or 5 times throughout the listing which models were compatible.

I honestly try my best to describe items as accurately as possible.

The listing says its compatible with samsung galaxy tab 10.1, 8.9 & galaxy tab2 10.1.

It also describes the connectivity as a 30 pin connector.

This buyer has a much newer model samsung galaxy 4 with a 4 pin connection and simply didnt read the listing properly.

It seems after finally reading it they then used the 30 pin c

onnector in their favour in the return process wrongly asserting that i claimed it had a 30 pin adapter in the listing.

Connectivity in the listing describes the connections on the dock, it doesnt imply an adapter for 4 pin or 30 models is included.

So regardless of the description they have now somehow assumed it included an adapter to fit her 4 pin connector.

Ebay has told me they have found in the buyers favour and now i have to also pay for return postage to receive a 2nd hand item back with all the retail pacxkaging gone.

Is there a number anyone can give me to call ebay and complain?

Is it even worth trying?

Thanks in advance for any advice?
