Despicable service - Makro Germiston online

I placed an online order with Makro Germiston on 06/06/2025 with delivery promised on 09/06/2025. My order was split with some items being delivered on the 9th and 10th of June 2025 and the remainder of my order promised by 13 June 2025. It is today the 27th of June 2025 and still nothing. I have tried numerous times to call the online order department at Makro Germiston but there is no answer, even Makro’s own Customer Care Centre can’t get hold of anyone. I have logged emails and phoned the Customer Care Centre endlessly to request cancellation and refund of my outstanding order as items are no longer needed, only to be told my order can’t be cancelled and refunded by the Customer Care Centre it needs to be cancelled by Germiston and unfortunately no one is answering. This is ridiculous, how can this not be escalated, what is the purpose of a Customer Care Centre if they cannot provide any assistance to a customer! Lesson learnt, no more Makro online purchases.
