Seems like a simple question, but I have conflicting information from my bank.
I have recently had a problem with the company, CashNet, who accessed my information when I applied at a sister company. I had a supposedly unpaid loan with them last year. So, they debited my account for $590. WaMu issued a provisional credit, but CashNet said that if a full credit is issued, they will continue to debit my account under different dbas.
ACH Services Department at WaMu said if I don't do ACH transactions, just go into a branch and ask for an ACH block on all debits.
