I have already seen it happen with other operators. This is the first time I got a call myself from Airtel guys. The guy was confusing as expected. Told me that my number was resubmitted to DND which is absurd, because my number was NEVER TAKEN OUT OF DNS. Told me that the process would take around a week and I might get spam sms during the period. He wants me to believe that spam sms would magically disappear if my number is in DND which incidentally it has been in for years now. Anyone else here on Airtel got such a call yet?
