There's lots of these schools in London. I know the LLC (London Language Centre) on 147 Oxford Street. Don't pay, won't pay, and have illegals working for them. Is Anna the Accountant from Albania still there? She is one dangerous cookie that needs treatment fast. You mentioned Immigration and Border Police, if they raided this place they would have a field day, and the Tax Office would be over joyed too to catch another tax evader. Its time we got rid of all these non desirables from the UK shores. Sorry to hear about your story, hopefully the authorities will act quick and shut them down. Name and shame I say, and here is a great place to begin.
