Airtel — Airtel - Calls and sms's from an unknown nos

Address:

Bangalore, Karnataka

Sir/Madam, My mother is an airtel user. In fact everybody in my family uses airtel. Its sickening to know that the hoax calls/ unwanted calls cant be tracked as to from where the call is from, whats the idea behind calling, who is calling at your end. Today morning, My mother got a call from this no [protected]. The gentleman said in hindi, he is callling from Delhi, she has won prize worth of lumpsum amount... some 50 lacs and all. My mother could not figure out, she replied no we dont want. That person has talked much things in hindi, god knows! and at last he said "kya nahi nahi bolte ho... " "I Love You". If this problem is very regular amongst airtel users, then why there are no steps taken to track or block such numbers from calling us and disturbing? Isnt there any inbuilt software or some application to be included in the SIM cards, to automatically block such nos? I am totally fedup with this. I request the airtel authorities to block the number as soon as possible so that she can continue with the service. number is - [protected]. Kindly do the needful, at the earliest.
