Delayed delivery and bad service

I placed an order on the 26th of January and was informed everything is "in stock" and I would receive the goods on the 1st of February 2019; on the 30th I received an email stating I would receive the goods on the 5th of February as there was a delay on one of the products. On the first I decided to track my delivery on their App and noted that the delivery date had shifted to the 6th; this became a concern for me as I needed some of the good by the 5th because they were bought for a friend who was leaving for Durban on the 6th. I contacted takealot and was told they would get back to me within an hour; this never happened. On the 2nd of Feb 2019 at around 9am I decided to contact takealot again, the call center agent said she would get back to me within 3 hours as she had to contact the warehouse to see if they can expedite the order of the goods that were available, this did not happen. I called them again before 1 pm and the person I spoke to said they needed to contact the warehouse blah blah blah (basically giving me the same story as the two previous agents I spoke to. I lost it and asked that my order be cancelled; they told me they cant, I have to wait for an SMS to say they have dispatched the goods for delivery then I can return the order ... What on earth is this, why must I have to deal with so much admin when they are in the wrong? And the last person I spoke to had the audacity to tell me I wont be charged for returning the goods; why would your organization charge me if they are the ones who delayed my delivery and did not even have the decency to tell me about it. I am so angry with this lack of customer service that I have decided I am no longer going to order from Takealot.
