Goods Never Delivered: Incompetence

Order: *** was not delivered but the app indicated that it had been delivered. After numerous email correspondences Takealot eventually arranged for delivery 5 days after the initial delivery date. On the morning in question the courier company phoned me and I informed them that the driver must phone my housekeeper when they arrived at my home, the despatch agreed that this would be noted and done. The driver failed to do this and did not make the delivery. Another 5 emails and 10 days after the initial delivery date the order has still not been delivered and the customer service people who keep replying without taking cognisance of information from prior emails have still not done what I have instructed Takealot to do. I want a full cash refund - not a credit note - for the goods that I have paid for and still not received. I do not want Takealot to try and deliver these goods fro the third time since this company and their couriers are clearly incapable of doing so. This issue must be resolved as per my instructions without further delay.
