Vodafone Idea — Porting request not generated

Address:

E123 shyam vihar phase 1 najafagarh delhi 110043

Since Vodafone is not able to provide data service to my location i am trying to port my number to another cellular network service provider. When i am trying to generate porting code i am getting below message.
"upc cannot be generated as there are subsisting contractual obligations with your service provider"

After discussion with idea helpdesk they asked me to visit Vodafone showroom. Showroom people saying that i have plan with discount so they discontinued that plan too but still not able to generate upc code. I am still getting same issue.

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

Please help me to get out of Vodafone network.
