eBay Hacking

Somebody has hacked into our eBay account - - twice in the last week! What this does initially on our end is when we try to log into our account with eBay, we can't log in. The first time, it took a few minutes to clear with with eBay's technical/security support...we had to reset our passwords, they took the hold off our account, yada yada yada. eBay reversed the listing fees so we weren't responsible for them. When it happened a second time and I couldn't get into our eBay account yesterday morning, it took a long time to get it fixed.

I don't understand how this is being done. We aren't getting emails about their listings being added onto our account (like we do when we list our own auctions). We aren't getting notices of questions from potential buyers. Finally, we aren't getting notices that the auction has ended like we do with ours. How does somebody bypass the eBay system on just their own merchandise while ours sits out there and proceeds as usual? All of our contact information is as it should be in our account so we "should" be getting those notices when somebody uses our account like that.

I have virus software on my computer. I have a firewall. Our passwords are a mix of everything we could possibly do so it is not like they are easy for the regular person to guess. We don't log into eBay on any computer but this one.

So, the question is...are they hacking into our account through something they are gleaning from my computer somehow or are they hacking thru eBay's security directly? Why aren't we getting notices of this person's auctions when we have auctions running at the same time that we do get notices from?

It's very aggravating.
