Qrioh Retail — OnePlus 9R holographic mobile cover

I ordered the Oneplus 9r holographic cover and on recieving the product i realised it wasn't holographic at all, just a simple coloured print. I simply wanted to return it and get a refund but i was denied that even though the company clearly states it has a 10-day return policy and it was clearly written that the cover is holographic. In contacting the whatsapp number and chatting with them, they offered me a gift card when in fact i need and i deserve a full refund. This is an outright lie being spread by the company and cannot be tolerated. No number of the company provided picks up the call, the customer service is bad as it can get.
