Well, you can have 2 alternatives.
1) Suck thumb and pay the fine,
2) Challange the system and don't pay. 
well, i have a friend that goes through erp with out cash card.
when letter came, is 10+$, never pay, 70$. 7x different. but i
think urs cant appeal because urs is dangerous. i park void deck
kena 100$ summon can appeal to mp. but if u student and u not
enough cash, then for this 1 month really, scrimp and save or get
pt job?
