[Resolved]  Quikr — fake and incompatible charger received with the phone

Website:

quikr.com

I brought a certified oneplus 3t on quikr, along with it i received a fake charger.
I was expecting dash charger (The only reason i brought oneplus device)
I think the seller is selling stolen mobiles.
I asked quikr for return and there reply was we dont care,
The executive told me "to do what ever i can do"
I am regular online shopper and never faced this kind of service.

The supplied charger charges the phone very slowly and funnily the battery drains if i am using the device while charging.

Please provide me information about what i can do
Also i would like to warn every one not to buy quikr certified mobiles
If you buy more likely chance is that you are buying a stolen device.
