Hi Dino,
I'm sorry that AC hasn't responded to you.
Elsewhere on this forum, posters have said that they're getting quick responses on other problems.
So it may be that they're not responding to problems with drug history because they've gotten so many drug-history coomplaints and have nothing to offer you.
But if that's the case, AC ought to reply that they'll let you know as soon as they have it fixed.
Cheers,
Carl Fogel
