1 month for a refund for money that's not yours!

My daughter ordered a few items in November and it was delivered on 23/11/2018 but 1 item was wrong. I called Takealot immediately and complained on Twitter. From there it was downhill. I received an sms that the wrong item would be fetched, but no one came. My mother waited at home for 2 weeks for the item to be collected. It was finally collected on 10/12/2018 and we have not received a refund. Takealot has ****** money while I stored somebody else's items for free. Only today do I get a message that the refund will reflect between 5-7 days. So 1 ****** month for a refund. From our end - we order, we paid, we got the wrong item, we stored it safely, we returned but still NO REFUND. Takealot now owes interest on the money due to my daughter. I've spoken to a supervisor Hanro and a manager Toefgha who made a ton of false promises. These are all warning offences and they should be taken to task for failing to adhere to a client's request. If they suck at their jobs, what should we expect of their subordinates? The item that my daughter ordered was meant to be a surprise gift for me and now I had to intervene and this ruined her surprise. She has no gift to give me for my birthday nor no money to buy something else. Takealot's handling of the matter has been nothing short of disgusting. I demand the refund to be done immediately with interest and a formal apology to be issued to my daughter.
