I bought a pony recently (last night, so the 13th), and paid right after winning it, but ebay told me it was still processing the payment after I completed the checkout. I found that to be strange and checked my paypal account, and it said the seller's paypal was unregistered and my payment to them was unclaimed. I messaged them about it, and they replied pretty quickly saying that their paypal address was different than the one ebay had routed my payment to. I messaged them back asking if they could check their ebay settings to make sure ebay had the correct paypal address, but they haven't responded again.
Earlier tonight I sent them another message essentially repeating that they should check their ebay settings and make sure their paypal address is correct so that my payment can be sent through, but didn't get a reply. I realize it's been only been a little over a day since my last contact from them, but I wanted to ask- can they open a NPB case against me when my payment is still in processing? With all the crazies out on ebay lately I want to make sure I protect myself (though it's entirely possible my seller is completely rational and just busy, I just don't want to take chances).
