Disappointing Makro online service

I recently purchased an iPhone online from Makro, confident that, as a reputable company associated with Walmart, they would provide excellent service. Unfortunately, I was mistaken. The ordering process went smoothly, and I received tracking number MAK***, so I eagerly awaited my delivery. To my shock, the package contained a plastic toy bicycle that I now have to assemble. I doubt it even costs R300. Imagine that compared to an iPhone! I immediately requested a return, which was recorded in their system. Two days later, I received a call from a representative named Boitumelo from the Germiston Depot. She informed me, “Unfortunately, you have to bring in the electronic device; we don’t collect electronic devices.” I pointed out that I didn’t receive a phone but rather a toy bicycle. She seemed unprepared and didn’t check the return information before calling. After some confusion, she acknowledged the return in the system and said she would arrange for the collection of the item . She then stated, “We will have to locate your iPhone.” I firmly told her I wouldn’t wait for that to happen, come collect your plastic toy and give me my phone instead. She said she would consult her manager about it. When I asked for a reference number for the call, she claimed they don’t provide those, but she was Boitumelo from Makro Germiston. As I wait for them to collect their toy and process my refund, I can’t help but express my disbelief that such a reputable brand will have such a flawed online store.
