Useless

I had placed and order online in early June 2024. The item was delivered, I had people come thru and instal the item. After sometime, I notice that the item was the incorrect item. When I called Makro, they had also advised it is wrong and they will contact there supplier. The item that was delivered to me, was between R600 - R700 at other retailers, Makro charged me R 1800. Anyway, they collect the item back from me, did their investigations and advised that they will refund me, this was end June. There policy is 7 - 14 days to be refunded. To date, I haven't been refunded and each time I call, I am told their is a technical issue or they don't know whats wrong. I am using my airtime to call Makro for my own money that's owed to me, so far I have been on the call with them for over 4 hours in total and I receive no feedback.
