received a reply on my request for details:
"Dear Sirs / Madams Regarding lot 406 from Nov 7th 2020 Auction held by SOFE Design Auctions We had to cancel this transaction due to a clerking mistake. The higher winning bid ($275)was awarded to another bidder who was bidding via another bidding platform. We use 6 bidding platforms. The clerk has made a clerking mistake by closing the lot too early! And since she/he opened the next lot for bidding she/he was unable to reopen lot 406 again to continue showing a bidding progression. In our practice it happens! In any case: Auctioneer's decision will be final. Auctioneer also does not accept liability for technology, website or internet failure, or unforeseen circumstances that may influence the execution of bids. This matter is closed now. Again, please accept our apology. Hopefully we'll have similar items in the future! "
you can guess what my action will be for similar auctions in the future with them....
