Recently i visited klcc and both times when i was about to exit, i scan my card 1 time, i heard some beep feedback but only showing me the parking fee, booth did not open. I scan again then it opens. After go back home then saw my card charged twice. Happened 2 times already after 2 visits.

Did you guys face similar issue? First time i paid using credit card, 2nd time i used TNG card just in case credit card is prone to double charge but it seems not.
