Leeco Le 1s — Received a downgraded phone post service

Address:

110053

My phone got dead in two months. Service centre took approx 1month in repairing.
Post repairing they handed over me a downgraded model. When i tried to contact service centre they r saying that they had stopped providing service for letv.
Very bad customer support service.
Now i don't want to use le eco.
I want my phone get replaced hand to hand or givey money back.
Le eco service is very pathetic.
