I followed procedures of revoking ACH for several payday lenders. Some complied. One did not, and in fact debited 2/3 of the original loan (something in the fine print I did not read perhaps? - learning lessons the hard way), leaving me overdrawn. Also bank issue - they didn't block it even though I provided copies of the certified letters I sent along with the receipts. I will file a dispute with bank, which to my understanding is their policy, even though I explained the laws (REG E) that I read about. More stalling, I imagine.
