I'm afraid I have the same problem. I attempted to edit a section of the map and botched it all up. The road I was editing was broken up into little sections. I tried to delete a section with the intention of extending the other section and ended up moving an intersection in the process. I've put it all back, but I can't report a bad deletion. Is there a way to contact the area manager to let them know that a deletion should not be approved because it was made in error?

Not at this time. The only feature that has an undo is the delete road, and you have to do it right then.
