You can ask your bank to block all debits to your account, and this will stop any fees from being taken.
My bank blocked all debits to my account last week so none of the PDLs I owe could get their fees. But in doing this, I was also unable to use my debit card for debit or ATM transactions and any checks written would not be honored. So basically, I was blocked from using my account as well.
Your other option is to close the acct. and open a new one somewhere else. None of the PDLs will have your new acct. info., so you can take back control of your money.
