March 2024, I made a payment of $580 for a balance of $579.68 on my GM credit card. I was expecting a credit balance of -$.32. Instead, I received a bill for $5.86 so called interest. This was despite my check posting prior to the due date. I felt this was a chessey move on behalf of Sachs.However, I will pay this fee. In addition, my GM card won't be the card of choice in the immediate future.
