Bank Fraud!

So yeah someone's been using my account and routing number to withdraw nice tidy sums of 100 dollars.
First two charges happened on 9/11 of all days with really obfuscated intermediaries, followed by another charge this Monday.
Honestly they talk about Credit Card fraud but my card wasn't compromised, plain and simple all you need to steal money these days is the account number, as every bank will list its routing number online.
