Takealot accounts department in disarray

On Saturday the 8th of April I bought a TV from takealot. Initially the order did not go through, but I tried again and the purchase was successful. I received an email from them to confirm that they have received the payment. A few hours later I received another email saying that I have not paid. I ignored this email because of the confirmation email I had received and also the money had been deducted from my bank account. Two days later they emailed me saying that they are cancelling the order since I had not paid. I was confused but then that was not happening for the first time with them. I tried to chat to them explaining that the money had been taken off my account already. The next day I received my order. No apology no explanation. Their accounts department is not organised. This happens all the time.
