Makro doesn't refund me for an item that wasn't delivered

I ordered a titanium entertainment unit on the 17th of November 2019 online. It was supposed to be delivered within 2 and 5 working days. The store failed to deliver within the specified time. I then called to check if the order was coming later on the 22nd of November 2019 but it was already past 5 PM and I was told all the deliveries for the day are done and they don't understand why I haven't received mine. I asked for the order to be cancelled immediately. It's 2020 and I'm still waiting for the refund of which I believe that someone somewhere there at the store isn't doing their job. When I call the online department, they tell me they'll follow up with the Carnival branch, some peope from the online department tell me that they'll check with the courier and some say they'll a follow up with the accountants. The matter is not getting resolved because all these people they never bother to come back to me with a response and each day I call, I speak to a different consultant and I have to retell the whole thing and they have to say the same thing, that they'll do a follow up and contact me. I want my money back, I don't have airtime to call everyday, it's costly staying on the line everytime while waiting for someone to pick up. If I'm not gonna get my money back, just let me know . I think I deserve to know if I was ****med by one of the biggest retail companies in the country because why else would Makro not want to give me my money back. Getting a call form the hellopeter team is also not helping in anyway because they sometimes do give me a call but the matter hasn't been resolved since.
