Staff are nice and they are chinese people, but not Australian. But can be more professional!

I pay the autotoll (road fee) by cash on the return day, but they didnt send me a recipt, the day after i receive my visa card was paid the autotoll again!! But i tell the staff of EZU, they cancel it immediately. Just i think they need to improve it, and i suggest we need not to pay by cash as we have dont have recipt!!
