Tata Docomo — unable to make calls

Address:

Kakinada, 533001

I'm not able to make any outgoing calls. It's just saying call is not allowed. I have recharged with 169 still no use. Thing is i'm getting the incoming calls but outgoing are going. Its keep on saying you are not allowed to make calls. From two days onwards it's been this way. Can you please find out a solution for me to make outgoing calls. I even tried turning off my mobile and switching on and off the airplane mode but still no use. Kindly find a solution this. Thank you
