Gail,
Thank you for alerting us to this issue; I'm not currently aware of this particular problem affecting Notre Dame students, but I'll take a look when I have a chance.
We currently upload PDFs to the PQ FTP repository and then mail the paper microfilming agreements in batches as they're processed. Our recurring issue with ProQuest (going on at least 2 years now) is that I no longer receive receipt confirmations when they receive our submissions, and I no longer receive invoices when the services are rendered. Eventually I do receive a past due notice, though, and then I have to request that the email me any open invoices. I still have open orders for May 2016 graduation.
