FIRST OFF I MUST APOLOGIZE FOR THE LONG POST.
The same exact thing happened to me. In Sept 2005 I sold 2 Louis Vuitton purses, 1
Gucci purse and a Louis Vuitton cosmetic pouch...all AUTHENTIC.
The buyer and I had exchanged quite a few emails before the auction was over. I emailed her additional pictures and video taken w/my digital camera. When she won the auction she stated she didn't want insurance. She also asked for my telephone number because I had stated that the sale was final.
I informed her that I would send the items w/Signature Confirmation. She received the items at the end of that same month. She never left me feedback nor did I leave her any. Now I had a funny feeling about the transaction because she asked all questions under one username but purchased the items under another. Done or so I thought.
This lady had the nerve to file a chargeback against me in Feb 2006. She stated I misrepresented my items. I called Paypal over and over asking if they got all the email correspondence I fowarded between us because I had kept it all.
I emailed her and told her that I fowarded all email correspondence and pictures/videos between us. Two days later she cancelled the chargeback.
At this point I'm thinking: Great I won, she probably thought I didn't keep copies of anything.
Two months go by and in April I get an email from Paypal saying that they were taking the money out of my account. Boy did I lose it.
They told me I didn't qualify for the Seller Protection Policy because she claimed that I "misrepresented" the items. I told them that they should take the money out of her account too because she never informed me or returned any of the items. I told them that I was scared that she would try to replace my authentic items with fakes. I also told them that she had sold all the items I sold her w/in 2 months of receiving the items.
I kept calling and calling for 5 days but no one at Paypal would help me. Then I received a call from a Paypal supervisor who had monitored one of the calls I placed. She told me she called this lady and questioned her about the transaction. The buyer told her that she filed the chargeback because she never received the items. LIE - I had the signature confirmation to prove it. The Paypal supervisor then asked her that if that was in fact the case, why did she state the items were misrepresented in the chargeback claim.
Well the Paypal supervisor stayed on the line w/the buyer and made her credit me the funds taken by the credit card company.
It was a horrible experience, and I'm so very sorry that it has happened to you. Hopefully you have copies of all correspondence between you two.
Don't give up. Keep calling and hopefully you'll speak to someone who is being monitored by a supervisor.
