Makro delivered the wrong product

On 5 June I came across an Oros 1L on the makro app for R6, 24 and placed an order for 50x1L. Very excited my order arrived very quickly on the 6th of June. Confused by the packaging and amount that was delivered I opened it right away only to find what was delivered was not what I ordered. What arrived was 50 units of Mr Orange 300 ml ready to drink Orange juice. I phoned straight away and informed the operator that what I received and what I ordered was not the same. She checked and confirmed that what I ordered was definitely not what was delivered. She tried to connect me with makro in Centurion but no answer. I tried phoning myself but also got no answer. I requested a return in order to get my correct order delivered. It is now 4 days later and still no response.
