Extortion by vmc

I'm a student from vmc we paid around 1 lakh rupees during the admission for dummy and were promises that we won't hv to give pre boards or practical. Now we have to give practicals which is still tolerable But the dummy school and vmc center are extorting parent's to pay extra saying ki baccho ke future ka sawal h The first' day we went to our dummy school we were asked to pay 5000 for school uniform later were made to pay 14K saying that we won't hv to give practicals but idk what happened with the money now we hv to give practicals We r Also asked to pay 8500 again for uniforms which most of the parent's hv already paid ( the 5000 i mentioned above) The School is giving out no recitps and is not accepting online payment we hv no proofes of the payment we hv made I hv already paid 5000 14500 now I'm again being asked for 8500 is this not extortion?
