Sorry, but cannot agree with you deserving the additional two certificates when you did not fly the stated additional 10K. If it is such great concern to you, you should -- as most of us here would do knowing we'd be short a few hundred miles -- have done another flight or segment. Why should you get any grace from AC when the measures are very clear.
And as others have suggested, the 2002 certificates will be so underused that you will be able to pick them up from people on this site quite easily.
Chill out. It's not as if you missed elite status by a few hundred miles, or because AC didn't bother to let people know they were discounting the required mileage in 2001.
