Faulty items returned - No refund, no feedback.

We purchased a TV for our company from Takealot. The TV was faulty - the HDMI ports did not work. We troubleshooted with different cables that do work on other TV's and it still did not work. We requested to send the TV back and receive a refund (either on our TakeAlot Account or back into the bank account from which payment was processed). They collected the TV from us on 03/05/2021 @ about 11:00 and said it will take about 5 working days for them to have a look at the TV and make a verdict about the refund (based on whether the TV was broken or not). I have tried following up numerous times after the collection about the status of our refund, and to date (20/05/2021), we still have received no communication about when we can expect the refund. This is ridiculous. They take days to reply to your emails and when you call in, they are not available, When will we be getting our money back for the broken TV you supp**** us, which has been returned?
