My last payment of a $3500 no interest installment loan was due 8/1/2018. My bank sent out a check for $150.00 which only $50.00 was owed on c7/30/2018. Regency is stating they did not receive the check by 8/1 instead they claim to have reeived the check on 8/3/2018 and charged me 818.33 in interst on a $50 last payment
