For the records, I won't discuss with someone like you

Someone like me? You mean somebody who actually knows what they're talking about and doesn't fall for the rubbish you post? Let's be more accurate, Turnoi... You won't discuss with me because you can't. Having an actual discussion, rather than just insulting or strawmanning, would show how little you actually know about the world of ESL teaching.

And you are wrong again: No training centre offers any value, and all of them are crap.

Now, you see it's biased and uninformed nonsense like that which gives you zero credibility. A sweeping generalisation based on no personal experience and without foundation. You do not know every TC in the world, you are willfully ignorant to even the most common sense.
