OnePlus India — One plus two

Address:

Kolkata, West Bengal, 700095

I had bought the one plus two thinking that it is a good phone. However within 6 months o[censored]sing the phone I am facing issues of latency and UI not responding, The screen would go blank and would not come alive for hours. The battery would not charge and the phone would give a message saying replace charger. When I took it to the service center they simply formatted and gave back my phone. They said the charger was working fine. I realized what a big mistake I did by buying this phone. I am sure the service center people also do not know how to solve problems faced by the customer. Now from today my phone has stopped recognizing any sim cards. Is there any way we can reach the parent company? Can we ask for a replacement of the phone ? BIG BIG Mistake to buy this phone. Also I want to make people aware that they should not buy this phone.
