Keeping Original Degrees of students

Location/place: Greater Noida

Name of company/service: Bakson Homeopathy Collage

Hi,
I wish to know that for what reasons the Bakson Homeopathy Collage greater noida keeps the original degrees and certificates of students admitting to BHMS, students are already bound to them by paying 154K at the time of admission.
do they torchor students further to the extent that they have fear that students will leave even their 154K
and also I wish to know that do they legally authorized to keep the original certificate for two years.
if not then how can they do it so openly.
