Oda classes - Complaint about Oda mentor teacher misbehave over phone

I enrolled my child in a bridge course and was assigned a mentor to assist with registration. However, I voiced my concerns about the refund process to the mentor, and my surprise, he became hostile during our phone conversation. I recorded the conversation, and I am now contemplating filing a report against Oda for the unprofessional behavior displayed by their employee. It is evident that Oda needs to take a closer look at how they train and manage their staff. As a concerned parent, I strongly urge Oda to implement a centralized recorded line for customer communication to ensure transparency. This is my honest and truthful account of the situation and the difficulties faced by parents.
