NIIT — refund for epro course

I am a student of NIIT Kankurgachi(KKG), Kolkata which was later moved to Camac Street branch. I have successfully completed my ANIIT Banking Course from Camac Street NIIT. But, I had also enrolled for EPRO course in 2015. I have paid 2200 rupees for the course. But, after two years NIIT told that they are not teaching EPRO course anymore. So, I requested for a refund as the course will not be taught. From April 2017 to now, April 2018 I still haven't received any refund. I requested the NIIT faculties several times but they did not respond positively. After finishing my ANIIT course, still I am going to NIIT every now and then for the refund which is very difficult for me as I have several job interview scheduled. Its been 1 year and still I have not received any assurance of getting my money back. In this time I have mailed to NIIT many times, most of which are ignored by the faculties and the center head of both KKG and Camac Street NIIT. I have all those emails saved. Maybe 2200 rupees is not a huge money but it matters to me as I belong from a lower middle class family.

Awaiting for your positive response.
