How can I reach a manager? I put in a request to receive a call back from a manager on 12/14 but still have not received a call.

Sadly, there is no way to get a "Manager".  All you can do is post your question here (As long as no one needs access to your account), use the chat feature, or request another callback. 

Thank you for bringing this to our attention, k-ksmschools-co.
