Terrible service from Takealot

I bought bath products which were supposed to be delivered on 14 May 2025. There was a delay with the delivery and my products were not delivered on the 14th as promised. On 16 May 2024, they delivered 2 of the 3 items ordered. The 3rd item has not been delivered yet. I have followed up with Takealot several times and the response from them is that they are "investigating with the relevant team" and will respond once they have feedback. I don't understand why a simple matter like this has taken 4 days (and counting) to "investigate". I cancelled my TakealotMore subscription because of this terrible service and the next step will be to ask my bank to reverse the charge.
