Is it worth re-visiting the Anglo-Spanish war of 1585-1604? You know, two armadas of warships shooting cannon at each other, raining hell-fire upon the other...I reckon you'd get your parts quick smart! Lol. (I cannot condone this suggestion, it is just a suggestion...)
Ebay did the same to me when I sold some camera stuff that never got paid for. The held it open for weeks and weeks which cost me sales to other buyers. I ended up giving it all to a friend in frustration and actually felt better for it.
I hope the Spaniard's send the parts.
Now...off you go, mobilise the armada!
Lol cheers my friend, I just logged into paypal and to no surprise they have pushed the refund back another 7 days, so I put in a formal complaint for all the good it will do.
I stopped using the site after a couple issues like this. The problem is that so many outlets use it to sell. Frustrating. Good luck with it though.
