There is a screenshot of the original e-mail that the company sent here. They state that 'according to your batch, we estimate that it would be better to continue working as a freelancer', where 'batch' is e-food's internal rating system.

I have no idea how you may be aware of a company's internal information, but the greek article you linked does _not_ mention rating system names.

Also, but when using e-food there's no way to actually rate delivery people, only restaurants (like you claim above with "Negative reviews from customers...").

Besides, the article this very comment thread belongs to also says "Efood drivers, which the company claimed had lower ratings, received a message" so what are you arguing about exactly? You're shooting the messenger.
