I think you should just drop it, because ebay is not going to do a thing about the situation. They are only there to make money not care if some is being rude to you. Ebay is like all companies in this world-money is the bottom line and nothing else matter in their world.
Move on. I hope you have a better day and you are not being a baby. Attacking you verbally is really ignorant. Sometimes venting on these forums really do help.
