How do I cancel an ach transaction agreement. My bank account was compromised.

[bluedeb · Accepted solution]

To verify the date that Federal funds will be withdrawn from your account, confirm that funds have been transferred, or cancel the transaction up to 48 hours before the date you designated the funds to be debited, call the IRS at 1 (888) 353-4537. 

If you have a state ach you would need to contact your state.
