Rude and Inconsiderate Parent

[learn-n-grow]

Last week a parent was supposed to drop her daughter off @ 12 pm. She called me @ 12:05 to let me know that her child will not be coming at all that week. I asked her if she could please give me more of a notice and she responded "I will let you know when I know". I was extremely annoyed by this as it was so inconsiderate. I msg her on monday to let her know that her daughter must be in attendance by 12 pm or she will not be allowed in until nap time is over @ 2:30. She then informed me that her daughter was not coming in that day and that she does not agree with paying for days her daughter will not be there. I informed her that I understand that she doesn't agree with it but she still has to make her full tuition payment by the end of the day (her payment is due on Mondays) and if it was not received that late fee will apply. She then tried to tell me that title XX doesn't pay for days that the child is not there (she is not even on title XX). I informed her of how title XX pays (even though she is not on title XX). She didn't respond. If she comes tomorrow (I say tomorrow because she doesn't come on tuesdays) without full payment, she will have to walk back out of that door with her child and she will be terminated. Am I wrong? If she does not show up tomorrow, she will be terminated immediately. She signed a contract that states she understands that payment still has to be paid whether child is there or not. Should I contact her tonite to see if her daughter is coming tomorrow or just wait it out? I'm beyond annoyed with this parent...
