I have a degree in Linguistics ( I got Hons btw ) ... I also have an International English Teaching Licence, meaning I can teach English in almost any country

Which you must have printed out yourself given that you know next to nothing about international standards of teaching and once said that "10% of my class is grammar. We do grammar activities like anagrams, word association, colour psychology and role plays"

All of which a reasonably intelligent parsnip could tell you are not grammar activities.

So if you didn't print it yourself, I'd be asking for my money back.

As for the international teaching licence... Please enlighten me as to what this is? I've never heard of it unless you're referring to a CELTA (or equivalent) or the ITC, perhaps?! And any teacher of ESL should have one of them anyway!
