Frustrated Tutor: What should I do about possible non payment of tuition fees?

[micromachine]

Kan phua stupid tutor, just look at how he collect his money. Or maybe all Michaels are plain stupid.

I am a private tutor who typically collect my fees at the end of the month. Lessons are held at my place so I am only in possession of the students'/parents' phone number.
