Probably payment on GS backend was processed late even if customer initiated payment on the due date. So customer was charged interest.
I was an early adopter of the AC during my Apple glazing days. Everybody has the same due date (end of month) and GS systems just could not handle the volume.
I remember an auto payment taking a week to withdraw from my bank account and applied to account. I wasn’t charged interest and didn’t have an installment at the time though. I believe installments were introduced a year later after AC was generally available.
