Reliance Jio Infocomm — jio is selling my number in spite of activating dnd

Address:

Plot# 1/159, Athreya Sharaba Appt, Anjaneyar Koil St, Vengaivasal, Next to Win Flower Play School, Chennai, Tamil Nadu, 600126

I keep getting marketing calls inspite of activating dnd for my jio phone number - [protected].
I keep getting marketing call every day and it is very disturbing and it is a kind of harassment for the customers.
With this i would like to luadge a formal complaint against jio that even though i have activated dnd jio is ether allowing these calls to pass through to my number or selling by number to the telephone marketing business like banking, education, etc.
