Hi I recently sold a pair of boots on ebay and sent them first class standard post. The buyer has contacted me to say they haven't arrived. Fair enough but I checked their feedback, they have sold items on ebay and have negative feedback for items not being sent, including one quite high value item. As royal mail will only compensate me up to £20 I will lose out on about £30 which I really cant afford. I am sure I'm being scammed and as the buyer's feedback is so bad and mine is fine, does the buyer have a case?
