i sold a buggy on ebay recently and have now had a message from the buyer saying it is broken.
it definitely was not broken when i sold it
i know ebay nearly always refund the buyer and now i am 
how can i prove that it was ok when i sent it? she wants me to pay to return it and then get a refund!! ffs
and if she has deliberately damaged it in order to claim a refund then how can i re-sell it???
i don't know what to do
can i refuse to refund/accept a return?
