SCS Processing help

Stupid as I know it was, I feel back into the payday loan cycle. I pulled myself out and I notified all of my lenders and was able to arrange payment plans/paid-in-full with all of them except Everest Cash Advance. Never heard back from them. When I revoked ACH authorization it was too late to change my direct deposit from my employer so I couldn't close my checking account. I did however have my bank put a stop payment to Everest.

Low and behold, the morning of my payday I see no attempt from Everest to ACH any money, but I see a check issued to SCS Processing for the full amount of my loan plus interest with Everest. A Google search says they're the same company.

I called the check fraud department of my bank and they basically told me that because I gave Everest my account information at one time their dba and affiliates can write a check under my name whenever they want and for whatever amount they want even if authorization was withdrawn without it constituting fraud. Is this right? I owed $40 on my principle to Everest, and their dba SCS Processing took $520. What recourse do I have?
