I think this way of purchasing is born to be full of problems. The only way this kind of a system could work is that ebay gives money to those who lose their money. It's as simple as that. You should not be able to use a service in a way that makes you lose money for nothing. I'm sorry that you lost your money, next time think about what the reality is like before you send money somewhere. I'm really sorry that you lost your money and keyboard!
