Ahhh drats, it's the wrong seller... 
On a serious note...
OP, welcome to the ebay discussion boards, sorry it is under such distressing circumstances for you.
Please forgive my humour, as I'm sure you're not feeling much like laughing atm. It's an inside joke between most of us here that I posted to help us pass the time by trying to fill the gaps before you hopefully return and provide us with a bit more information.
We need to know the details of what's transpired between yourself and the buyer that's lead you here,.so that we can better understand just whats happened and hopefully be able to offer you some helpful advice.
I see that you sell preowned fashion wear, so I'm guessing the buyer is accusing you of selling fake designer labelled clothing/accessories. I also see that you haven't received a negative from a buyer recently, or in the last 12 months. So perhaps the buyer in question hasn't yet left feedback ?? I also see you are only a relatively new seller, so this must be especially upsetting for you.
You've come to the right place for advice, as there are some very knowledgeable & helpful sellers here that also trade in fashion wear & who I'm sure will be only too willing to offer you some very sound advice.
