I am unable to use the call barring feature. it was working fine before but i forgot the call barring password . i tried a few password and it got blocked. now i cant change the call barring password. it get error "Barring password blocked". i tried contacting Airtel customer case many times but as per them its a cellphone feature and suggested me to contact Nokia for the same . i explained them by sharing the manual of the Nokia model that its a service provider server and they don't agree. please get the Call barring password unblocked and share the new password with me. My number is 9810849066.
