Purchased online training course in English for se...

Purchased online training course in English for self-study. In the classroom, a huge number of errors, constant technical failures and malfunctions, the sound does not work periodically. At the moment, the sound is not working again and there is simply no way to do it. Comments are left, but no one gives answers. By telephone refused to provide a contact person in charge, and connect with a qualified staff to solve the problem. On methodological issues there is also no one to talk to. It's just a divorce for money and zero responsibility! Disgusting school and disgusting unprofessional mercenary approach to customers!
