Company refuses to fulfill my order because of a mistake on their side

<p>I place an order yesterday 20th of July online on Takealot website the order was completed and paid for later that afternoon I got a call from Takealot informing me that they cannot fulfill my order ask him why and he said there was a listing error which results in them unable to fulfill my order I told the gentleman I will not except what he has told me you must put it in writing in an email to confirm what mistakes I've made he was admin that they can only file a return request and that the item will not be shipped and return will be noted on the system this is unacceptable I clear it all the gentlemen I will not accept a return back and that he must put it in an email this morning I get a return received note from Takealot saying of return item when I'm not even received it and I did not even request this I am very unhappy because they should fulfilled the order because they have the item in stock and the mistake is on their side</p>
