Clicks refuses to deliver products paid for

I am utterly shocked, angry, fed up, disgusted, and just about any negative emotion you can think of. I placed an order with Clicks Online for collection from Clicks Honey Crest on 24 November 2017. It was my first time using their online shopping service and so I didn't pay too much attention to not getting a notification after payment was made. Just assumed I could track online and I'd be notified when my parcel is ready for collection. A few days later, I went to go check at the store and because I didn't have a reference number, they used my ID to check. There was nothing for me. The following day, I tried to track online, and to my surprise, I found my items were sitting back in the cart and not checked out. I called them and was told the matter would be investigated, I was issued a reference number. I heard nothing back and called again after the 48 hour turn around time had passed and I was told the lady working on my case would call me. Days later, I called again and I was told the lady would call me. This time I was also told I would need to send my bank statement(the bank charges for this), but the lady would call me back. I eventually received a call back but turned out to be accidental, they were trying to call a different client and not me. I told them I had my bank statement ready and need to know where to send it. Again, she insisted that the mystery lady would call me with the details. Mwanwhile Clicks, I've paid for toiletries and had to go buy over and above that because I didn't even have toothpaste! Something Clicks seems to not be concerned about at all!! I am feeling the worst about Clicks right now. Do something!
