Vodafone — VI UPC code cannot be generated as there is contractual obligations with your service provider

I am trying to port my number to another cellular network service provider. When I am trying to generate porting code I am getting the below message.
"UPC cannot be generated as there are subsisting contractual obligations with your service provider"

The Vodafone service desk is unable to provide any solution and their network service is worst after their coloration with the idea.

Please help me to get out of the Vodafone network.
