Failure to back back Return Money

I ordered a JBL speaker on Friday 09 June 2023, the speaker got delivered on Monday, 12 June 2023! The very same Monday i logged a return because this speaker was very small and the cables where short and couldn't connect to me TV,. On Tuesday, 13 June 2023 the item was collected for return, when the item was collected the delivery guys help me wrap the item and they collected two boxes, a big box with the speakers and a small box with all cables, remote and other items. I have been following up on my return and TAKEALOT is telling me i wont get my R12999 refund because i didn't return everything. I literally packed every single item that was delivered to me!!! The delivery guys can attest to that because they saw,. TAKEALOT doesn't know who they sent to me to collect and now they cant track whatever is missing. I want my refund. This is not the first time they do this, they always make excuses when they have to refund customers. This is the worst service ever, i have been calling their customer service everyday to follow up and i wait on the line for over 20min to speak to a consultant. The day this company shuts down, will be happy and millions of South Africans who experience the same issues will be happy too!!! I want my refund. R12999 is a lot of money!!!!
