My bsnl was not working since last 5 days when i went into roaming from BSNL to MTNL, than coming back to BSNL network.
when i try calling, Gives, "sorry you have no service" "sorry you are not allowed to use this service" (yes two messages one after another)not able to use outgoing and sms/data.

I checked my balance. my amount is there, but says your service expires on june 10..

can anyone please tell me what's happening? and if my time is out already why they still keep my balance?
