OnePlus India — OnePlus 3T - Current from the handset's hearing part !! Service center says out of warranty in less than 4 months??

Address:

Gurgaon, Haryana, 122002

I bought oneplus 3t on 31/01/2017.in mid of april-2017 i got current while talking on the phone and of course lost the grip of phone and screen got damaged as it hit the floor.in first week on may-17, i went to oneplus service center to have the same changed as the phone was under warranty! The service center tell me that this does not come under warranty and i'll first have to change the screen which will cost me 10k and after that they will check if the current still comes!!! It sounds stupid!! The phone has 1 year warranty and still they tell me that it is out of warranty!! The current could have been deadly if in hands of a child!! How can this be neglected and be told that it does not come under warranty??? I requested for repolacement of the handset only as i do not want any risk/chance of recurrence of thsi incident. They denied taht as well!!! I am kind of lost on what to do with these cheaters?? The service center is with name "esskey outsourcing pvt ltd"
