I would have to agree. I had to packages go missing on the same day. They had tracking one eBay one amazon as I have only had one package not arrive from eBay before I thought it was suss. Well let me tell ya I was on the phone to AP and I wanted answers. So I would think this buyer would have to be having a problem if its real.
I think that having sellers report her to eBay to investigate would only be a good think. If its all above board she has nothing to worry about but if eBay think its suss it could save honest sellers.
Just as I hate dishonest sellers I also hate dishonest buyers. It ruins the whole experience for everyone
