Whenever a school claims to use another schools ATO or has anything even remotely suspicious about the validity of their certificate - run.
A lot of the schools operate like this and so do a lot of non aviation related companies for various business reasons. Even CTC have subcontracts for part of their training and I would hazard around 50% of schools have some sort of slight name difference.
Your responsibility : Know who your paying money to - and pay by credit card so you can reclaim it if necessary.
It's all a mute point if they can't sponsor you for a visa.
