Bad customer experience

On 27 December 2022 I went online to purchase a pair of sandals hoping to give them to my mom for her birthday which was on 3 January. When I made the purchase I selected the instore collection option for Canal Walk because I work in that arra plus I thought it will be quicker. I chose the size as it was available online. I waited patiently and even past my mom's birthday with no update on the order. On 5 Jan I called Milady's to track my order amd I was connected to a guy at the Canal Walk store who promised a call bck from the lady who deals with online orders, I waited until a fee days later I got n email from Sthembile Gumbi apologizing and stated they are still sourcing out for the shoes from othe stores as they did not have the size and promised delivery would be around the end of the week which ended on the 15th of Jan. The week ended with no word from Milady's, on Monday the 16th I wrote back to them and until today I haven't heard nothing from the Milady's team. I am now waiting for 3 weeks for just a pair of shoes. When I ordered the shoes there was no indication online that they did not have my required size. From my experience with online shopping, if the store doesn't have the size it is either greyyed out or it will have an X across so you can't choose it. I do not wnmat anything from this *********** store but my full refund. Their service ia appalling, their customer service is extremely poor.
