My wife is a prepaid Airtel subscriber and now days she is getting anonymous calls from different numbers. Out of which, one number is from Airtel only. 9633352162 is the caller’s number and I think, the caller is a student. Can you check this number and block his all out going calls? Can you locate the caller? If yes, please does it fast? Now, time being my wife is switched off her mobile. Once I get a green signal from you, the number will be activated. Otherwise I don’t have any other way than moving to some other service provider. read full review »
