Hello.,
This is jayanth sharma. I have an airtel number [protected] which was ported to vodafone last year. And i didnt get the recharge so it was deactivated. But i want that number back where as vodafone service said me that after 3 months you will get that number back in mother network. So i am trying for the number in airtel office near my location. There is no response at all from the office guys. Please do need full.
