Paid H&P Capital...did I just make a mistake???

I just paid off my husband's outstanding, 5-year-old Advance America payday loan that was with H & P Capital. I know that he did, indeed, owe Advance America, so this is not a question. But a couple of things bother me. They pulled the whole, "the statute of limitations on this is up tomorrow and it will be turned over to the police and charged as a misdemeanor." But the "bad check" that they had was post-dated. From what I understand of the law in my state (Indiana), you cannot be charged with check deception on a post-dated check to a payday loan company. Am I understanding this correctly?

So here I went and paid them via Money Gram. Is that even going to go to Advance America? What if I called the local AA tomorrow to verify info and insure that the correct place was in fact paid? Do you think that's a good idea? I don't really know what to do. I hope I'm over-thinking things. Also, if they did give me bad info in order to collect the debt, do I still have recourse under the FDCPA? Or is that a non-issue now that the debt has been paid?

Thank you for any info you can provide. I shouldn't have been so frantic, but I only had about an hour to make a decision and I didn't want my husband (who has never had any criminal charges against him) to be charged with a crime. And I know...there are no debtors prisons and all that. But check deception is a very real thing. I just didn't know if the description applied to this situation.
