Lodha Group — Promotional calls - infringement of privacy

I keep getting minimum 6 calls every day from Lodha group despite the fact that I have not subscribed to the calls and have never shared my number with Lodha group. I have told the sales guys not to call me and keep chasing me as I keep important calls throughout the day and these promotional calls are absolute nuisance in every sense

This is infringement of my privacy without my permission. Very annoying and cheap behaviour from Lodha. STOP CALLING ME
