Nokia India — misrepresentation of information and attempt to fraud on service

Address:

Hyderabad, Andhra Pradesh, 500032

My Nokia 6 phone under warranty had an unexplainable display issue which required it to get replaced.
As it was covered under warranty, I had contacted their customer support and they directed me to give the phone for repair at their "authorized service partner" - Delight Solutions (Secunderabad, Telangana).
I was promised that the repair will be fixed within 10 days, but it has been a month till now. I'm unable to reach the service center through any means of contact. They recognize my number and cut my call, avoid my mails. I don't have any update on the repair.
I sought to Nokia customer care for help, they initially seemed to be responsive for a couple of days, and said they'll take up the issue on priority with the service center. But then for the next 2 weeks they also decided to ignore all my mails. They refuse to provide any mechanism of escalation.
It has been a full month now, and i don't even know if my phone is in safe hands anymore or has already be sold of to someone else.
