Never received my order period!!

I bought Slippers at woolworths on the 3rd of June through their online platform and because my purchase was less than r500 I had to pay for them to be delivered to me. So I did all that the expected date for my delivery was the 9th of June, on that day I received a missed call and it was the head of Woolworths wanting to deliver my order was late around 17:40 but they were unable to reach me.

What was alarming is that on their app where I was checking the status of my order, it has changed to being delivered hence I never received anything. I called their customer service to make a follow-up regarding the order but surprisingly they claim it's been returned to the warehouse but it's an assumption. They will send confirmation that it's back at the warehouse even now nothing.

I sent countless email this whole week no one attempted to call me back or even respond to my emails, it feel as if I lost my money because they are not making any effort to resolve my issue here. I need to know whether I'll be getting my money back or will I get what I paid for it's as if they lost my order and just updated on the system that I received whereas I didn't receive anything. I feel that they expect me to just keep quite and move on whereas I lost my money too.

Please kindly help a sister out because this is pure daylight *******.
