Little different Ebay story- A pin I was looking for for months came up as a lot for live auction 2 states away.
Contacted seller and got approved for bidding.
The day of the auction, before live start tossed a bid on the item to make sure I was approved, interface worked and that I was at least in the ground floor.
Item comes up, I go to increase bid... nothing. I'm locked out. 60 seconds go by.. Item gone for $25 more than opening bid I tossed down.
I call Ebay and they admit they have no idea why aside from the claim that the software used is under control of auction house running live event. I tell them "guess what, you lost money and I'll not waste my time doing another live event on Ebay since I jerked around my whole weekend to make sure I was available for the auction and got boned" They admit they can see I was approved for bidding and that I placed a bid early in the day.
They said they will escalate and look into it.
