Airtel — Unwanted calls from person

Address:

Madhya Pradesh

Respected Sir,

I am getting unwanted calls from [protected]. This is airtel number. I am a school teacher and somebody calling me on night and says i will catch you from your school and he is abusing me so badly. When my brother calls on this number then he did'nt pick call or switched off his mobile. Please solve this issue as soon as possible.

Thank You
