Ordered: oneplus one 64 gb on apr 23 2016 by order id: 245491

I received my order today morning (26th april) but when i opened the packaging, it had a 16gb oneplusone box. I thought that it's some error with the box and maybe the phone inside is in good condition but to my surprise, there was even no phone inside.

The order was for a 64gb oneplus one. The packaging i received had 64gb written on it but the actual box inside the packaging has 16gb written on it. I've attached the necessary pictures.

I've complained quikr multiple times but they are not willing to provide me a replacement or refund. They are saying that they sent a phone but i didn't receive any. Now i am stuck. They aren't responding to my emails and twitter complaints anymore.
