This for the third time Airtel is asking for documents for verfication documenst, once when I purchased the SIM, once got message message last year then too i submitted the document proof @ Airtel Gallery after which all was ok and now againi get this message which was also not very clear as it was asking submit documents and get free SMS and after few days my cosed my outgoing calls, if the service provider is not able to maintain the documents, why is it down an again asking for verification documents?
