Makro Refusing to Refund

I have had a terrible experience with Makro online. I returned headsets and requested a refund and this was in September 2023. I have called, emailed and submitted all documentation that the customer service has requested of me but till today(December) I have not received my refund or any proper communication from them as to what is happening with my refund. I am extremely disappointed with the service I have received and honestly I expected better from them. I have proof of all the emails I have sent and the responses that don’t give any proper feedback from them. Recently they are not even responding to my emails after claiming that finance is handling the matter and no communication has been received proving that someone is attending to my query.
