Hey guys! I was scammed on eBay recently.($85) The buyer bought my item, paid for it then I sent it to him and he left positive feedback. A month later he filed a charge-back dispute through his credit card company (PayPal notified me), they then asked me to provide information of my shipping and everything. I did this with all of my positive feedback from the same/similar items. A month later (today), I find out that the credit card company ruled in his favor so I am now out of $85. Any suggestions of what I should do?
