Hello All,
My cashcard was in the IU when I passed through the gantry at PIE yesterday morning
but the red light keep flashing and a long beep sound.
Call LTA up and they mentioned that there is no cashcard in my IU and a summon will be served within this week

I had taken out the cashcard and re-insert into IU and the green light is on. I am not sure if its due to the cashcard or and IU but this morning, they work fine

So is there anyway for me to appeal?
Thanks
