Dear Scott,
Like any employer, we do not automatically contact and interview every candidate that applies for a job with us, even if they are TEFL certified. We have limited positions to fill and look for various criteria in making a decision as to whether to reach out to a candidate or not. This does not make us a scam or a "buch of cowboys". Nor are we totally incompetant. We are all qualified English teachers as well as responsible recruiters.

Our client has some particular qualifications that they wish for us to be focused on and perhaps you just did not match that particular criteria. After all, not every English teacher is a perfect fit for every position, just as not all schools are an ideal fit for all teachers.
Regards,
Sean
