egay was being gay for me the other day - it failed while trying to process a paypal payment - In the end it turned out I HAD paid....TWICE! Once when it failed, and once again when I tried again!
I contacted the seller, ebay and paypal. ebay sent me a standard 'nowt to do with us mate' the day after, paypal sent Mr Kumar along the day after with a vague grasp of English who basically said it's ebay's fault, and the seller came back the same day with an immediate refund! Cracking seller - nuff respect!
You'd have thought ebay and co would want to investigate the problem in case there's a more widespread issue!
