Vodafone India — unable to make outgoing calls since a month

I've been chasing the vodafone customer care guys on chat email no one is helping me out. I'm not able to make outgoing calls since a month I need an answer. Why should I pay my bill for that month? I need this resolved please else cancel my connection.
As soon as I click on call button the calls disconnected basically not connected at all. The only advice the representative who I finally got hold of had remove sim and insert again tried a 1000 times didn't work either selected network manually no results.
