Thank you for the suggestion on emailing multiple appellate authorities. So far I have been sending all information to the Srinagar and Bangalore appellate authorities. I have received no response yet.
However, googling it gave me this - https://susam.in/blog/infosys-tcs-or-wipro/
Now I have chosen to hide it from the list of all posts but it is still accessible via the direct URL. The primary reason for doing this is that often new people I meet go look me up on the web, come across my blog, then come across this post, and then talk to me about this post. While I still stand by what I have written there, I would much rather talk about other topics such as technology, programming, or mathematics which I enjoy talking about much more.
That said, one would be surprised at how much non engineering exists also in “product companies”.
Jio is known for being really bad for customer support. Their services work well until they don't, and support is often clueless. The appellate ladder rarely looks at email. Their entire setup is flawed; they have no concept of SLAs or oversight. I've had my experiences during complaining about spam calls.
All one can do at the moment is keep making noise on social media and hope someone fairly important takes a look. I would advise that you still send emails across all the appellate authority email IDs at the timeline prescribed (send to higher authority level after prescribed number of days have passed with current level not giving replies), so that you have the paper trail they say you should have, to cover yourself in case they start asking questions.
It'll likely be a long fight.
