sorry to hear that you've been mugged off, but looking at the ebay listing, i don't fancy your chances of a refund.
He states they are red and they are indeed red (albeit sprayed) and he does say all items sold as is.
All i can say is that you put it down to bad experience and this is a warning to everyone else who was thinking about buying some.
there are too many con artists on ebay at the moment, so the best thing we can do is to all stick together and warn each other of these rip off merchants.
PS I hope i am wrong and you do get your money back.
