Easiest solution would be to take the paperwork (copies) of the receipts and baggage claim and head back to your friendly airport! I see you are STL .. that would be the simplest solution! Let them take care of it!
I guess the next question I have is WHY did you have the bag repaired?? In all cases (I lost count) where AA damaged/destroyed by luggage I simply took the empty bag back to the airport with the claim paperwork and said 'HERE Fix it!' and they did! Granted I was sans bag for a while (but as an EXP you gotta think of luggage as an expendible investment and have a couple of extra bags!).
In several cases, the damage was so severe I got a brand new bag! I have never had a complaint with AA Baggage repair .. I just let THEM take care of all the details!
