During the visit your bank employees told above mobile will b registered soon. But still it is not registered. Until now from the day of opening account i had never received any sms to any of my number but your bank has been continously charging for sms. This is fourth time i am requesting for number registeration and your team could not able rectify my problem. This time i am expecting a positive response from your end. Please do needfull..
