If it didn't happen to me......(An update)

Received a letter in the mail today from my student loan company informing me that a pre-payment of $885.00 had been made to my student loan and that I would not have to make another payment until July 2011, but that my interest would still accumulate on the outstanding balance.  No shit?  I wonder how long it will take these mental-midgets to figure out that I not only reversed the payments both times they tried to cash the erroneous check to their bank account, but I also sent them the correct check to make my payment for this month?!?
