Contract got terminated after 1day of being a teacher!!: opiniones de empleados con el puesto de Empleado anónimo en DaDa

I got an offer letter,I accepted it. Then on the day I suppose to start to teach,I get a welcome letter. Then my time slot begins,and I have no students for 3hrs. I sat infront of the computer waiting. The next day,my contract gets terminated,without prior notification or details as to why?i phoned China,the lady was clueless aswell. Then I emailed the coordinator,she never reply. A lady replied and tells me that she is so sorry,but there is a bug in the system ( I will attach the email on all social media for the world to see how badly I was treated). Then she says in the email ,”anyway you never attach your teaching certificate. I have a Masters degree from the University of Liverpool .And in my interview they were aware that I don’t hold the TEFL . On the website it says within 3months or employment I must obtain the certificate. I purchased the course ($250), and I already started the course. I bought new headsets ($59), a new webcam ($99), a lighting system ($40), many props ($30), 2 new golf blue shirts ($150), I did all the online training for DADA. And I get treated with such disrespect. I will let everyone know in AUstralia 🇦🇺 to never work for DADA !!
