Has anyone here dealt with Michelle McGrath-Davis?

I'm posting here on behalf of Uschi Huppman and two more German collectors who have purchased Lonestars from Michelle and not recieved them. They were supposedly being prepped by a Jane Schneider so Uschi emailed me to ask if I had the horses but I don't offer prepping services and have never heard of Michelle.

Does anyone have any advice for Uschi? I guess sending a registered letter might be the next step; does anyone have an address?
