Vodafone India — connectivity issue

Address:

Allahabad, Uttar Pradesh, 211001

My mobile no. Is [protected] which has vodafone connectivity. Whenever i am trying to make outward calls i am getting a message 'not registered on network'. On making calls to this number a voice message saying 'this number is not valid'. I am not receiving any message also. All these are posing very serious problems for me.. For past few months the internet speed on this number is also very slow continuously causing troubles for me using vodafone network. Please resolve the issues immediately otherwise i shall have no option except to switch over to some another network.
