Bad training experience with Etsia

I was contacted by one of the recruiters for a position at Etsia - home schooling. I had to attend some online training. Two days after training I was informed that I don't qualify for training anymore. I don't know how they made this decision. I spend a lot of time on a intro video for this company and sacrificed my time and money to attend training just to be told after two days that I don't qualify anymore without any valid reason. I don't think I was treated fairly. I feel like they made a bias judgement. It was a complete waste of my time.
