Would you be Frustrated?

So I am a Nanny and I was watching this baby and the mom stopped coming in the middle of the week and wouldn't pay me. We had a flat rate fee each week and she wouldn't pay me and then I kept saying hey you need to pay me. Then she sent me $1 and said that's all you get thanks for your service. But I didn't do anything work I made sure I did everything I was supposed to with that baby. What should I do
