eBay

How do you get Ebay to listen and act on fraudulent transactions. The complaint system is automated and faulty,

I can't sign in to sell. I can sign in and do other things like relist etc. My password is recognised. But when I go to sell by each of the various ways I get asked for a password and it is not recognised. Whats going on?

My wife and I use the same computer but have different Ebay usernames, email and PayPal accounts, and separate Ebay bills. In the past Ebay allowed us to post auctions separately. Now when my wife tries to sell it switches automatically to my account...
