CIBIL Report — vulgar calls

I got a call on december 5, 2019 with phone no. [protected] in the morning around 11. First he asked my name and i refused next he asked me if i liked sex.
I told him twice that if calls me again i'll give this no. To police but he did not stop. I had to put him in my phone's blacklist. Please block this no. As i don't want that any other girl gets this kind of terrifying calls.
