Consumer Redressal

I was doing MCA from ICFAI university, My concern is that I have not able to complete MCA within the registration period( 7 years). But now I am serious and continue with the same, but University is trying to refuse to do the re-registration. But at the time of registration, they have mention in the prospectus that student will get registration(DeNova Registration) for 2 to 4 years. Please let me what we can do in such cases. Now I am want to continue with the MCA programm, but university doesn\'t allow the same.
