From my BSNL Mobile number (9470567488) i am not able to call on some specific number from last 6-7 days. Earlier i was able to call those numbers but not now. All of those numbers are BSNL also. Also i tried to talk to BSNL Customer Care representative but they put me on hold for 20 minutes around and then themselves disconnected the call. This hanging up of call by customer care executive is not 1st time it had happened many times back too. After that I don't know how but we are not able to call them as if they have done something so as we cannot connect our call to customer care.
