Takealot being untruthful

I tried to keep this on the private chat, but having regard to the response I got from Takealot on Messenger, I have to post it here. So first , they satae that the refund has been completed, and it depends on THE BANK'S processing time. Then, they say TAKEALOT can only process my request within 7-10 working days:

Me: I ordered and paid for a laptop on 15 January 2019. Tracked my parcel yesterday and found out that my order has been cancelled. Takealot did not even let me know about this via email Order # ********** 8. Be that as it may, I phoned Takealot, the lady and asked about my money - was told it was placed in credit on my takealot account. I said no, I want a refund. She said she did the refund to my card as we spoke on the phone and said she will send me confirmation via email. I still have not received the promised email, nor the supposed refund!?

Takealot: Hello, Freddie. Thank you for reaching out to us. We can confirm that your refund was indeed processed yesterday the 24.01.2019 and depending on the banks processing time, it can take 3-5 working days to reflect.

Me: Payment to you from my account was immediate. There is no bank process that takes 3-5 working days. That is absolute nonsense. I work with bank and inter bank transfers (from and to all major banks in SA and abroad) on a daily basis. At most, it can take 48 hours. Please send proof of the refund (not just a confirmation letter - actual bank proof) to me immediately to **********

Takealot: Hi, Freddie. Unfortunately, we can only issue a refund after 7 - 10 working days.

Me: So, you first confirmed to me that the refund had already been issued/processed and that it can take 3-5 days to REFLECT. Now you say, you it will take 7-10 days for you to issue the refund? You are contradicting yourself. Send me proof of the refund now.
