I had ordered 3 covers and 1 screen guard with order Id 3984691
But the cover of redmi note 4 is having a defect as it is not fitting on the phone and also the screen guard that I have received is of OnePlus 5 and not of OnePlus 5t.
I have mailed the company about the same and they told me to make a video for both the items and then I got a reply that they will refund the amount for screen guard but after that there is no reply and even there is no replacement or refund for the same.
