Neuro Investment Advisor — hacking phone and keep calling about stock trading

I also received call from neuro investment advisor company, the caller asking me about all trading details and other, so i simply asked him that how he got my number? I do not live in indore mp, not even visited in past. How he hack my number? I sent email to neuro investment advisor company and other government institute representative for personal identity security reason.
His lawyer sent me legal notice because i cc to gov. Official
And i also expose other fake stock trading advisory companies from indore who called everyday in indian public.
And trading advisory companies caller being rude, using bad words if we said no, we are not interested for stock trading and stop calling again. But they dont listen... They keep calling daily.
Well there are more than 100 fraud companies in indore mp... I dont know why sebi give them licence for trading.

Those companies misguiding, fraud, scam with you.. Hacking phone number, aadhar card, pan, bank detail etc

Please aware and send email to government official, police officers, collectors, sebi, bse, nse so they help to indian public and punish those "trading advisory companies"
