recently taken over support for a very complex drupal 7/Civi 4.7.x site (which I'm happy to say was very well built by the initial team).
One of the issues that we've found reviewing things is that there are a number of contributions that were entered by the staff of the organization that are listed in civi as complete but do not show up anywhere in authorizenet. Other contributions entered by donors themselves were processed and paid but these have fallen into a void -- and these are some large donations.
As you can imagine this is causing a lot of stress. People thought they donated and never got billed; the org thinks it has money that was never processed so actually does not exist.
Has anyone seen anything like this in the past? I can't go back in time and fix the broken donations but what can I do to try to make sure this does not continue to happen?
