Credit card companies use a number of tricks to levy fines on your account and collect as much as possible. The Consumerist showed yet another example of this practice when they allowed automatic withdrawls to continue even after accounts have been closed and the have ceased sending statements. In this case, a $38 late fee was imposed... for nothing.
From Consumerist.com:
When Capital One "closes" your credit card account, they'll continue to
allow automatic withdrawals even though the account is closed. But they
won't send you a statement—you know, because it's closed!—so that
you'll end up with late fees. Quenten experienced this first hand when
he closed his account recently, and now Capital One has sent his
account to collections over a $38.00 late fee for two 38-cent charges
that he never knew about.
