Unless your calculations are different and AA has made a factual error, I am not sure why AA would negotiate against itself. Selecting an EXP is a way of sending a message that it won't tolerate the practice from anyone.
I suppose that you could offer $2,000 and see what happens and be prepared to send in the full amount on the 30th if you have not heard back.
AA;s history is that if it did this to OP, there will be a lot more of these out there.
