Dadlani says the unknown person has been calling singer Sunidhi Chauhan, choreographer-director Farah Khan and his composer Shekhar Ravijani ever since the song "Sheila ki jawaani" was released.
Now Dadlani has put up the concerned person's number on Twitter to seek revenge.
"This guy, +31613566735, has been harassing Shekhar, Sunidhi, Farah, me, ever since 'Sheila' came out. He's very irritating. Time for payback," tweeted Dadlani.
He has urged his Twitter followers to irritate the person by either messaging or calling him.
"Thank you all for your... I'll remind you all again tomorrow. I wanna harass this m***n, as much as he's been harassing us. +31613566735
"This guy is utterly nuts, keeps crank-calling. See if he can take it! I had no choice but to let him see how it feels. He's a psycho, and deserves a taste of it," added the composer, who is behind hit songs like "Chhammak challo" and "Desi girl".
