Take some responsibility Makro!

Ordered a computer screen. Received updates via my app that it’s delivered but we got something different from The Courier Guy. We called the Courier guy back as there was no waybill nor invoice in the package. They just told us to contact the shop as they only the deliverer. We phoned Makro and was advised to log a return. I want to know who got my screen?! No one wants to take responsibility and why about the R3k I spent?! Can someone come back to me and give me a detailed response of what transpired and what will happen? Do I get the screen or are you giving my money back?! Also Makro if this is not your fault cancel your contract with Courier Guy! I don’t care who’s at fault I bought the item from you!
