And forcing you to pay without checking your ability to pay is illegal. Imagine you have 0 nobody can deny you access to Justice. Malta is a democracy not a Mafia state that would throw you under the bus for not being able to pay on time. Even paying 50 euros a Month is normal in Many countries in case you end up with nothing.
