We have a buyer who stated she has processed her payment for an Ebay item she purchased from us. She used the Auctiva notification - check out process - and says that the payment went through, however we do not show any payment posted in Paypal, Ebay, or in Auctiva - Auctiva reflects the Buyer has not completed the payment. She has attempted this twice, and now I am wondering after reading all these messages if there may be an issue with using the Auctiva checkout.
