Yaantra — Phone not yet delivered

On 26th oct 2021 I received a call from yaantra representative..and i was highly entertained by him telling that my phone would be repaired within maximum 2-4 days. On 27th October 2021 my phone was picked up from home. And after that next day I received a call from yaantra that my phone has dispaly problem and back panel damaged. They told me it would cost me 5500. I told them I would let u know and same day i told them that couldn’t afford this much and my budget is max. 3000 hence they told me i will get it done under 3500. I approved the same but after some time i called them back after 10 mins.. and told them that its not in my budget so don’t repair it and return back the device. But the engineer who’s repairing my phone told me that i started the work and assembled all the parts and the phone will be ready by today morning. And it is almost ready.
Inspite it was not in my budget i asked them if you have started the work and the phone is ready and will be delivered by tomorrow kindly process the same.
But next day I didn’t receive any update. And the same continues till next 10 days.
I’ve received no update. They neither pick up the call nor call back nor reply nothing.
It’s been more than 10 days no information is received.
And now I’m irritated by their service.
And I’m not going to pay them a single penny
