There are any number of messages coming on my mobile from these numbers +919686446386, 9845574037, 9743900731, 18002096767, 09222200919 I am registered for the DND still these numbers continue to send messages on the mobile. The Bangalore Airtel is not doing enough to see that their customers are not harassed. I tried calling the call center too but no joy. If this continues I may be forced to change my provider.
