Special education issue

Hi My 2 yrs 9 months old child has been recently diagnosed with autism(July 2017). We applied for his admission in Cambridge , Noida in nursery because it was mentioned in the forms, does your child need individualised education plan( does he has any special needs ). He was rejected in interview because he is a special child(autistic and needs individualised education plan). I don't understand why school took interview and rejected him. I called school but receptionist told me that they don't have any such special education or educators to teach mentally slow kids. However, teachers told me they do have special education. They took money for registration and mentioned in the school form that they have special education even though they don't have. Because of this I am in stress. Then my question is why school took registration money( why did they mention in forms) if they did not had special education, in case they have then why they rejected knowing that special education is for autistic kids/special children and there is no point in taking interview as they already need school's help and such kids have learning issues. Can I ask for refund of registration fees. Is there any law which says that all autistic kids can be admitted in any school without interview. Generally all autistic children need special education(one to one) in order to learn because they don't understand in groups.
