Airtel — deactivate call barring service

Hi team,

This is regarding deactivation of outgoing call barring service on my sim having no.[protected]. Last couple of weeks, i was facing problem, that i was not able to making any outgoing calls and messages and i am able receive calls and messages. I was getting "outgoing calls barred" prompt. I have contacted to customer care. But they could not resolved my problem and its not fair part from airtel to blocking services with out providing proper information to customer. Currently i am at overseas. I gave enough documents while i was taking documents. Please send me the password to de-activate barring as soon as possible.
