It's a bit heartening to hear that they will take notice when required and if you do persist.

We have recently had some damage done to our defect ratings and FB on our other selling ID by a buyer who clearly scammed us. We were sure we had not made the exact same measurement error on the 8x items she bought from us. One we could understand but not all 8. So we let her know we were not happy but did send out the replacement items she was demanding. She then left us 6x NEGs for our troubles. The other two she must have left inadvertent POS because the comments were negative.

We got some pretty conclusive evidence a week or so later when she tried to do the exact same thing to another seller but sent the message to us by mistake. Claiming that the order was received but it was short on item counts and/or lengths.

So we are now trying to get ebay to see that if she has done it to us and tried it again with at least one other seller they should remove the retaliatory NEGs she left us. They will be able to see all messages between her and other sellers and if this pattern persists often enough then surely they ought to find in our favour and restore our good account.

We had an update message yesterday from them saying they were still investigating the case.
