The Souled Store — Refund/Replacement denied

I had ordered some tshirts and polos from souled store, the total quantity of the items in my package should be 6 however i have received only 4 items. The items are even mentioned on the bill however i haven't received them. Those items are being showned as delivered on the app however i haven't received them.
Luckily i recorded an unboxing video too of the parcel i recieved.

The items which are missing are :

1) Solids: Denim Blue Colourblock
2) Pokémon: Mewto

The souled store denied the claim and said that they had shipped and delivered all the items even though I'm having proper unboxing video of the package i received.

I'm retrying to contact the customer support and everytime they tell the same story.

Please send me my missing products.
