ISBM — Extension course fees

Hi, I am currently pursuing DMS in IT. I would like to extend my course by 6 months as the family was suffering from Covid and it took a lot of time to recover, my father also passed away and my mom is still undergoing treatment for cancer. When I requested for an extension, I was asked to pay an amount of Rs.15000 for 6- month extension. When other institutes are doing this free of charge (my friends are doing courses from other institutes), then why is ISBM charging such a high fees and not considering Covid situation on humanitarian grounds. Please let me know if anything can be done for this. Would appreciate an early response, which I usually do not get. I had also requested for name change which has also not been done since the beginning of the course.
