Poor quality of the course

My classmates and I were disappointed with the course from administration assistance to the teacher and facility. It was not organized, teacher was not well trained, the administration assistant and sales representative were not responsive and professional. I was following up on April 2 for balance of payment prior to the course but response was late, in the end I was charged for late fee and until today I have not received any response on this. The teacher was not able to lead or demonstrate in the class in effective way, the session was messy and teacher could not guide or answer questions but asked us to read the materials. The facility was poor such as printer did not work, internet was slow most of the time, classroom was in poor condition. Finally, my certificate was printed with wrong name and till today I have not received it.
