Angry customer

I went to Woolworths Alberton city January 23/24 there was a nice pair of Leather block heel I wanted, unfortunately there was no size 8, I took the shoe to the till and I was helped by Tshepiso/Thepang by the shoes department till. She checked for me which stores that has size 8 and she found Heidelberg having, she phone the store to order the shoe for me to be brought to Woolworths Alberton. She told me it will take 2 weeks for the shoe to be at Alberton which it was fine by me. She said when the shoe arrive they will call me to come and collect. A week before the 25th February I went to Woolworths as I didn't get the call to find out bcs I was around there, when I get there, the shoe was at the Customer service nobody cared to call me, I didn't have money with me, and knowing it was their fault not mine, I asked the lady who was helping Siphesihle to keep the shoe for me until the 27th I will come and collect as I just passed to check if it didn't arrive?

She asked another lady I forgot her name, she explained to the lady that it is not my fault but the customer service department, Siphesihle promised to keep the shoe for me. On Thursday the 27 I came back very late, so I went on Friday around noon, spoke to Siphesihle that I am here to collect the shoe, she first acted surprised, then she went around as if she was looking for the shoes, I spotted her by the dresses standing with a colleague chatting while I was sitting there patiently waiting for her. Then after a while she came and told me a story that I don't understand, she said immediately when I left she put the shoe by the till and the colleague took the shoe and she doesn't know what happened to the shoes, I was so angry bcs she personally promised that she will keep the shoe for me hence I went to when I get to the shop.

I want to know is this the kind of treatment that I/we as Woolworths customers must get, or colour of the skin works at the branches where mostly they serve African customers. I am so angry and disappointed at the same time. Could Woolworths management look into the matter
