Makro refund still outstanding 7 weeks after item returned.

I did an online purchase on 02/04/2023. Was emailed that it would be delivered by 07/04/2023. It was eventually delivered on 12/04/2023 and I returned it, requesting a refund. Request was acknowledged by Makro online on 15/04/2023. Item was collected from me on 19/04/2023. Email received on 26/04/2023 that refund is being processed to the account from which I paid for the item.. 15/05/2023 Email received that a refund is due to me. I submitted bank details. 15/05/2023 Email received that my details are being forwarded to Accounts for a refund. 30/05/2023 Email received, asking if refund reflects yet. (It didn't). Despite NUMEROUS phone calls and additional emails, I have to date not received a refund NOR a date on which to expect the refund, nor any other progress report at all whatsoever. When I phoned to speak to a supervisor, I kept holding on and kept speaking to the same person who never put me through to a supervisor. My question: Is Makro bankrupt or something, that they just don't refund? It is 06/06/2023 today and still no refund nor any updates on progress.
