Dear Teacher XX:
I am very sorry to bother you in your busy schedule. We are the parents of XXX, and we have learnt the information that our son will leave the school because of tuition-fee. As his guardians we hope that you can handle the withdrawal procedures for my son. Please do us a favor, and we are really very grateful that you tried your best to urge him to stay. I wish you and your family having good health and good luck.
