I am a regular seller on ebay. I have two ebay stores and I have a buyer recently bought a similar item at both of my stores. He bought some rubber lip which is measured by certain length. He bought one listing with 235cm and one listing for 400cm. After that, he disputed in Paypal without contacting me claiming he only received 100cm on each parcel and also claimed they were damaged during transit. Paypal again back the buyer and request the buyer to return the items for a refund which he surely willing to do. Today I received two boxes with papers in it but not even the leftover 100cm. This is purely dodgy which make use of buyer protection in Paypal to get free products once in a while if not often. What can I do? It is not about the money but the anger which I felt in this country which make use of the return policy. Any advise will be good. Currently appeal the cases but still waiting for Paypal to get back to me. 

Feel so disappointed while you are doing the best for the buyers.
