Returned item unaccounted for???

I returned a pair of defective headphones to a takealot branch in my edgecombe on the 03/06/2021. My account shows return cancelled on my account however my headphones were received and in possession at their warehouse. I did send an email with query and have not been given any feedback. I just get a string of replies saying they are looking into it. Very poor system and a real hassle for a return. I still do not know what happened to the headphones and it seems like I am being ******. Someone needs to be accountable and i need my refund or exchange.
