Reliance Jio — UPC Code not provided by jio

My phone number is [protected] and I am trying to port out from jio but whenever i send message to 1900, i get message that your upc code generation request can not be processed. I tried to talk customer care multiple time but they respond that this is noy in our hand we can not do anything for you.

My request is i will going to get upc code by jio only because currently it is my network provider but rather than helping me jio is not providing me upc code and forcing me to stay with their network.
