Account Department

I haven't received any feedback from Spark school head office regarding my statement. After I've submitted all the proof of payments and email confirmation but still receiving email. I'm still receiving homework and project emails whereas my kids are now at another school. No response from Accounts department on the numerous emails, they don't even bother to return my calls. I left numerous messages. I need someone to call me back ASAP or I will lodge a formal complain with *******ion Watch or District Office.
