Jio — Code redemption

Address:	New Delhi, Delhi, 110032
Website:	Jio Pvt. Ltd.

Hey, i generated a code from my jio app, after the code is generated it is showing that it was already redeemed. Whereas i haven't redeemed it.
I wasted my 4 hours on standing in the que, what the hell is this? Even the Reliance store manager said that we can't do anything! I'm calling jio customer care since last 3 days more than 50 calls but not even a single response from jio.
Do resolve this issue.
