Please stop ignoring me

I've tried several time to be heard for my legitimate complaint, and I have been ignored across multiple channels. It's sad that I have to resort to public naming and shaming, but here I am.

A few weeks ago, I purchased a Defy Naturelight fridge. At the time, Makro was running a promotion where they were giving away free Cadbury chocolate slabs with every fridge - a cute gesture that was appreciated. The issue however was that the website was glitching - when I tried to add the deal to my cart online, the total was not correct and it appeared as though the system was trying to charge me about R120 or so for the "free" chocolates. After trying several times unsuccessfully and also attempting to reach out to the online chat (who only rep**** a week later), I couldn't come right with the website. I then went in-store the next day (something which I try to avoid doing during these COVID times) to buy the fridge from the Germiston branch. It was only at the till when I was paying that I realised that the delivery charge for an in-store purchase is more than double the price of an online store delivery. Had I purchased the fridge online, it would have been a R90 delivery, but in store it was R200. So the irony is that no matter what I did (purchase online or in-store), I was forced either way to overpay by about R110.

I know that it's not a fortune of money on a R8 000 fridge purchase, but it's a principled matter - I was inconvenienced to go in-store because the Makro website wasn't working as expected, and then I arrived to find out that the whole trip was for nothing because the amount that I saved on rectifying the online store glitch, I spent on additional shipping charges because for some reason in-store shipping costs 122% more than online shipping does.

All I asked for was the following: 1. To have my complaint taken seriously and for the website glitch to be fixed for other customers. 2. For an in-store credit for the R110 that I was effectively over-charged.

I don't think that either of those are unfair or unreasonable requests, but alas I have been ignored on social media, the live chat, and surveys.

Hoping that someone can resolve this for me.

Thank you
