Looking at the T&Cs I noticed something I hadn't noticed before:

This Bonus Aeroplan Miles offer is only available on the first $80,000 in net annual card purchases on your account (meaning all card purchases by all cardholders, at any type of merchant); after which Aeroplan Miles are earned at the regular rate on net card purchases. The $80,000 annual limit will reset to zero on the day after your December statement is printed. Terms, conditions and eligible merchant categories may change at any time without notice.

This is kind of bizarre because they way it reads is only the first $80,000 you spend is eligible for the bonus, not a limit on bonus amounts you can earn. Bizarre. That said, I just called about this month's points not posting and the rep escalated to a manager who knew about the problems and posted the bonus points manually.
