NIIT — Certificate of course not issued

Address:	Jaipur, Rajasthan
Website:	www.niit.com

Sir,
I have joined NIIT in May, 2015 and I was pursuing the GNIIT course (duration 3 yrs.) but due to their false commitment I had to leave the institute in 6 months only.
Then they told me that I'll get a diploma certificate for doing this 6 month course within 90 days and I left the institute in mid of the November 2015.
And till today its more than 90 days and they haven't issued me my certificate and after doing calls to them they continue saying that some process is going on and till today I haven't received it.
I had send them mails too for this purpose and there is no reply from their side.
