I terminated their services in January '07. I just typed up a letter telling them that effective immediately, I would no longer be using their services for the purpose of settling my debts, and hereby revoked my authorization for them to electronically debit my checking account, any further attempts would be considered unauthorized and fraudulent, and I would advise my bank to file an affidavit of fraud.
I went on to tell them exactly why I was canceling my contract with them, asked for a refund of all money that was in my settlement account as of that date and then sent the letter via certified mail/return receipt requested. Just to be safe, I also went into my bank and had them block all future debits from Hess Kennedy, in case they ignored my letter.
I did not ever receive any kind of response or acknowledgment that they had received my letter (other than the post office sending back the return receipt with a signature). I also did not get a refund of any kind, so I started calling and calling, to no avail. After months of being ignored, I finally filed a complaint with the Florida BBB and the Florida Attorney General's Office because that is where their office is located. Their "office manager", Adam Foremane, responded to both complaints with a lot of crap, but did refund the money I was asking for. I think I received my refund check from them in July.
