Aircel — refund my prepaid balance in bank account

Hi consumer court,
I am aircel customer for more than a year now. I have around 500 rs bal in two numbers [protected] and [protected]. A month earlier suddenly all the services of mobile network was stopped without any prior notification. If aircel network is not going to start in future, i request them to refund the money present in our prepaid sim to our bank account. I have talked to aircel representative at aircel express centres, but they said they can't do anything, as company is # down operations. This is totally unfare to shut down network without any prior notification. I want my money back.
