I searched for help with this issue, but I had a hard time finding a similar issue, so here goes. I had a buyer open a case against me via PayPal saying they did not authorize a purchase. This buyer made an offer on my item & I accepted. A couple days passed with no payment or contact from the buyer so eBay opened a NPB for me (I have it set to automatically open). Exactly 24 hours before the case would close in my favor, the buyer paid- so I shipped the item the following business day. I even contacted them immediately after they paid stating I'd ship the following day. I've received no contact from this person. This is my first issue as a seller, so I want to make sure I either keep the money or get my item back. Please help!
