MyCard charged interest on full payment.

[Johnnyaok]

My card charged interest even though the amount was paid in full before due date. Does this show a fault in their system or human error. They did reveres the amount after I contacted them, but I wonder how many others who don't check there statements very well might have missed it. Support dont know how or why that happened They did compensate me around $20 was credited on my next statement. Be aware check all your cc statements .
