25 days and no clear answer to my return, no product received back or a refund

I bought a Midea washing machine in January from takealot, it started making noises in July and then in the beginning of August is started tripping the power, I logged a return on the 6th of August, it was picked up on the 7th of August and the 9th of August it was sent to the merchant, we waited and waited, I emailed takealot just to be told the merchant has 21 days to give an answer okay fine we waited, 21 days passed no feedback and no updated on the return log, I emailed again just to get an apology and the will revert back, no answer after that, I emailed again, same answer, I phoned, same answer, I wanted to speak to the manager or supervisor and all I am being told is they will revert to them, phone again this morning, same answer and being told there are 3 open emails "with a response" but this response is basically the same response I have been getting for days, so basically after 21 days I need to get a full refund, it has been 25 days, 4 days past the 21 days and nothing just the same answer. In my eyes takealot and the merchant are *****ing from me as they have my money and the product I have bought, I want a supervisor or manager to contact me, this is now takelot`s responsibility as this product was sold under their site so they need to take action and refund me.
