TFG/foschini online shopping is a ****

I had bad experience with foschini online shopping on the 29 May 2020 I bought four bags from foschini online shopping at first they delivered one bag,during second delivery they delivered two bags without proof of purchase little did I know that it was a **** plotted inorder to cover their tricks of *****ing from customers. I have been sending them emails enquiring about the bag which was not delivered and know they are saying they delivered everything. How can I claim the item that have been delivered, why do they have to separate items that were ordered on the same day, because you want to ***** from customers. I called, send emails and they are not doing anything.
