Amazon Missing Item: Ordered 2 Sofa Covers, Received Only 1

I ordered two pieces of the product “2024 Sofa Cover, Large Stretchable 3-Seater Sofa Covers, Silver Gray, from Homodowsky” from the seller Kiikooo through Amazon, for a total of approximately EGP 3,600, with cash on delivery, under order number 406-1246784-9393956 in the name of Nadia M***. The order was delivered on Tuesday at around 3:00 PM, but I received only one sofa cover instead of the two pieces stated in the order, even though I paid the full price for both items. There was no invoice inside the package showing the quantity, I have no way to contact the seller Kiikooo, and I have not received a response from Amazon Customer Service yet. The delivery driver's phone number is +20 115 925 7***. I request that Amazon urgently review this order and either send me the missing second sofa cover that I have already paid for or refund its value, because I paid for two pieces but received only one.
