Tushar — harassment

Address:

Dear sir/madam,

I've been receiving a calls and texts from the number ([protected]) and ([protected]) and is torturing me everyday, i've been receiving messages sexually from this person and i came to know recently that he's following me everyday till my home and had been observing from past two months.
I do not know what to do, i'm literally scared and unable to take any action against, hence, i'm writing this complaint and would like to keep my identity secret.
Please help me with this issue, i'm terrified everyday, i'm an employee as well who works at night in bangalore, so, i'm terrified if that guy comes at night and does something to me.

I stay at hal and probably i would require a protection or something.
Could you please block this number or do something with this so that i won't be receiving calls or texts from this person?
