Kotak Mahindra Bank — Harassment calls from kotak mahindra bank

I have recieved a calls from this no. [protected].
But they are calling so many times, using filthy language. Kindly ask them to stop this.
Harassing people is illegal. They are calling some random people that i only know asking them to pay money.
Harassing them also calling them 20 times a third person who is not related to this matter at all is not correct.

I am going to file a police complaint about this.
