Collected for repairs, and still no update from Makro

I had a product returned on the 20th of March and it was collected on the 22nd of March 2023. Until today I have not received any feedback from Makro besides their representatives telling me they sent it to the supplier and there has been no update from the supplier about what is wrong with the product. its May now and I am the only one who is constantly calling them and the representatives keeps on telling me that they will follow up and revert to me and still I will have to call for them to tell me this over and over again.

I last call on Friday and a female representative assured me that she will personally follow up as she could pick up that the other representatives I had previously spoken to, did not follow up on my calls and they had closed them without speaking to the supplier. I even sent an email and they boldly closed the call because the supplier has not told them to what is wrong with my product.

I bought the product from Makro and for them to tell me bull about the supplier is unacceptable. I'm a client of Makro and not the suppliers, so for them to keep telling me about a third party that I don't know is a load of ****. I want my product replaced if they are struggling to find what is wrong or give me my refund.

So I want answers as its been too long, and I hate that I always have to fight publicly in order to get their attention.
