I am very disappointed with Takealot’s service

I am very disappointed with Takealot’s service. I placed an order because it stated the item would be delivered the next day. After payment was processed, I was informed that delivery would only be the following week, Tuesday the 27th. Because I urgently needed the item, I had to buy it from another service provider. I requested a refund and spoke to Kabelo.ST, who confirmed that the refund had been processed. Shortly after, I received an email stating that I would not be refunded and that the money was placed into Takealot credit instead. This is unacceptable. I do not shop on Takealot regularly, so credit is not useful to me. I spent additional money elsewhere due to incorrect delivery information. I am unhappy with how this was handled and I am requesting a full refund to my original payment method.
