Reliance — my outgoing calls are not responding...

Address:

For last 2 weeks my reliance number that is [protected] is not responding outgoing calls... Incoming calls are all right there is no problem in it... But i am not able to call anyone... Whenever i call it shows engage... Due to this i had to buy new sim to make calls but this one reliance number is very important as it is given in many important places to contact such as school...
