Order #*** Estimated Collection from Later Today - that never arrived

I have never received a parcel for next-day delivery, even though I paid for it. There is always a problem. If you can't do it, don't advertise it. Then I would rather wait for the fee delivery in the next two days. I bought a walker for my elderly mother hoping it would arrive on 30 September (as paid for and promised by Takealot) but by 17h00 I had no confirmation SMS and the tracking app said that it was shipped at 12h46 and I live in a city. I'm so disappointed again.
