Lack of customer service

I purchased items on the 23rd of September. I immediately queried delivery because I specifically chose items that can be delivered same or next day. In addition to that I have a subscription with the company that allows me to get same day delivery. I called the call centre spoke to a Faith who said she will arrange for my delivery the following day. I had to keep following up with her but no feedback till this day, the next agent I spoke to seemed like she wasn't sure of what she was doing and lastly I spoke with Lutholwethu who sounded keen enough to assist. After several hours of speaking with her I still have not gotten assistance or feedback from the company
