OnePlus India — Mobile phone oneplus 3

Address:	121006
Website:	ONE PLUS CUSTOMER CARE

My one plus 3 stopped working in 5 months of purchase and i have a guarantee on purchase. The phone was picked up by one agency for repairs but are asking 25000/- for repair as they said the main board is faulty due to some liquid gone inside which is totally false as the phone stopped working while i called someone while it was charging. I lodged the complaint complaint id 1470000 and after lot of follow up was asked to handover the phone to another repair agency at nehru place in delhi and it will be done. However after calling them today i was asked to deposit 18000/- to get the same repaired as this will not be approved. I have big doubts on the credibility of the repair centres as i am cheated twice
I am really fed up with this company as there is very poor service and even doubt the product quality a big question mark
