ISME INTERNATIONAL SCHOOL OF MANAGEMENT EXCELLENCE BENGALURU - Facing problem with refund issue of PGDM course fees from international school of management Excelle

This is to bring to your kind notice that I, Jayesh Bhagchandani took admission in ISME(Bangalore) in PGDM program with marketing specialisation on’.....date’. The total fees for the course was *,**,*** and out of that i had paid **,*** on **-**-****
I had doubts whether i will be able to understand whatever will be taught through online classes so i took the permission of the authorised people from ISME’s Management to first attend some classes and then will pay the fees or else they will deduct some amount and return the rest out of the **,***.
Sir, after attending the classes for * days I understood that its not easy to cope up with the online stuff for me, and also my dad has started facing some financial problem so I need to take a drop this year.
I informed the management through mail and call that i need to cancel the admission, they agreed upon that in no time, but its been ** days they have not responded to any of my mails regarding the refund, everytime they give a new date.
Kindly, look into the matter and help me out as soon as possible.
