Disputing ACH debit incorrect amount to recipient bank

Not exactly a tax question. This ACH debit to recipient's routing bank somehow got converted into a bill pay check. The recipient is not responding to overpayment, should I submit a CFPB claim to the recipient's bank demanding the overpayment to them be refunded back to me in form of ACH? The amount I was told initially to transfer over by the recipient was incorrectly inflated, hence why the overpayment

A similar issue happened with a wire. Overpaid to recipient, recipient received but refuses to refund the difference, what options do I have to pressure the recipient bank?
