I've been robbed!

Someone charged $2000 on my debit card. Thing is, I have my debit card in my wallet. And the ONLY thing I EVER use it for, is to pay my school payments. And just after my last payment on July 2nd someone charged $2000 on it. Which means someone probably took my number form the school. This makes me VERY angry. As if i wasn't disgruntled enough about this school. We're having a meeting with the director after class today and i'm all riled up. Some shit is gonna hit the fan. I'll let you know what goes down.
