This network has become such a harassment nowadays where i receive 4-5 calls a day regarding their promotional offers and ads.that too while riding or when in meeting or while expecting some importane call. i finally SMSed to activate DND(Do Not Disturb) to 111 for which inturn i received a message with a registration number saying that this querry will be responded on 3rd of NOV.am still wondered why they need 5 weeks to deactivate this service(harassment)... Friends i recommend not to opt for this service...
