I have received missed calls from +92 numbers 3 times in last 3 -4 months and received 4 calls from “Unknown” number which shows as “Private number” if i go back to my call history. From the unknown number the guy speaks in hindi and asks all nonsense questions as where did he call? who are you? etc.. etc… Airtel customer care call centre guy states that he cannot take a compliant as he dont have an option… can somebody fix this.
