VLCC Institute — course completion certificate not being given after 3 years of completion

Address:

VLCC Institute Of Beauty & Nutrition,103, 2nd Floor , Sreela Centre Above Treat Restaurant, Under Flyover, 1st Main Road, Gandhi Nagar, Adyar, Chennai, Tamil Nadu 600020, Chennai, Tamil Nadu, 600020

Hi,
My spouse completed a course (Chemical Peel & Microdermabrasion) at VLCC, Adyar branch, Chennai in 2016. It has been 3 yrs since then but the institute has not issued the course completion certificate. I have been following up multiple times on a constant basis but the institute is unable to issue the certificate. There is no complaints forum at VLCC and I really do not want to go to consumer court as I want to avoid further delays.
Regards,
Gaurav Tyagi
