Vodafone India — not able to port out and not able to change my sim ownership from corporate to personal

Address:

Pune, Maharashtra, 411013

I have vodafone sim from which i want to port out to jio. I tried it but it is failed and i asked about reasons so every csr gives me different reasons-
You have outstanding amount
You have coroprate sim
We already processed request but failed from jio side

I tried changing my sim’s ownership but vodafone store said - you cannot change it
Tried migrate to prepaid but vodafone store said that they don’t have migration form.

This is worst experience and intolerable.
Vodafone should really think about their customers as i have used it for 3 years but no good service from them.

Please resolve this asap otherwise i need to take strict actions against vodafone legally.

Thanks
