Online purchasing

Let me start by saying I am a huge customer of foschini and really love their clothes especially their shoes. On 24th September I bought things online as they where running a sale. Firstly I was disappointed at the manner they do their deliveries especially during the pandemic. Every day a courier would come to my house to deliver one item. 3 weeks later I then call the group to find out where is the rest of my items as they issued me with invoices and they tell me that the courier got hijacked. So I asked the consultant that if I didn’t call when was I going to be notified? He tells me that I was probably going to be notified once the claim was processed, which actually made me angry that TFG don’t care about their customers. So now I ask them when will I get replacements for my items and I was told that I will get a refund instead. So I told them I do not want the refund and want my items because they where on sale and now if I have to repurchase them again I would pay more than what I did, and all I got was sorry Mam. Why am I as a customer being punished? And since they have claimed for what was hijacked why is it a problem for them to give replace my items. I am extremely annoyed and disappointed.
