How the 1st time becomes the last time

This is how my first-ever order with Takealot is going: I ordered one book on 4 Jan & expected delivery date was given as 23 Jan. Rather a long wait in this e-commerce age, but I thought let's support local business. On 19 Jan at 15h57, just before delivery date, Takealot notifies me that the delivery is delayed. I ask for specifics & am told that delivery will be by 29 Jan. However, it turns out Takealot will get the book on 22 Jan, so I indicate that I expect the book in my hands by 17h00 on 24 Jan, for which I get no confirmation, after interacting on email with a total of 4 different people, none of whom acknowledge or seem to understand my reasonable expectation, or do anything to minimise the delay. And empty phrases like "apologies for the inconvenience" & "thanks for your patience" just increase my annoyance. It seems Takealot is more concerned with making things convenient for itself than meeting reasonable customer expectations. Takealot also seems to think it a good idea to maintain an "email wall" between themselves & customers, & provide no effective complaints or escalation process. All in all, a total let-down. Takealot won't be getting any more of my business, there are other options that involve far less hassle.
