Horlicks India — worms found in women horlicks

Address:

Coimbatore, Tamil Nadu, 641035

I bought woman horlicks for my pregnant wife and the first time when she put in the milk she found a worm (With white body and little black on head).
This is so unhygienic and could have damaged my wife and the kid.. I want to lodge a complaint against the company in real and make sure they are punished well.. If any one know which is the right place to go please let me know.
