Was assessed late fees because Alliant changed its billing and I continued paying monthly bills according to my monthly schedule that has by practice been always acceptable -- without incurring fees. I requested change in due date to accommodate my schedule and Alliant said could not make change. I demonstrated that change could be made and it eventually was without informing me. Alliant also claimed could not credit my bill despite the fact that I'd previously received credits and since the change have had credits to my bills. Summary, Alliant said could not change billing cycle and could not do credit. I've experience both personally, so I know that Alliant has lied to me regarding both matters. Credit my bill.
