Worse customer service ever and lack of communication

I am most frustrated by the lack of consideration for customers. I bought a fridge from Makro Riversands, it broke and I got a credit note from the manufacturer. Now when I called Makro customer services to find out how I get the fridge back to the store so that I can get my refund, I was transferred to the store where I was kept on hold for over 2hrs because apparently the line is not working. The switchboard had been giving them a problem for the longest of time and the store has an alternative number which is not published on their website. I sent an email and also there no reply. I ended up driving to the store where I was informed by the sales person that the phone has been giving them a problem and they have an alternative number which the call centre agents did not give me. Now the issue is I am not willing to drive back to Riversands to get my credit after they have collected the fridge hopefully on Monday, 02 June 2025. I had to throw a tantrum for them to make an alternative, the alternative being that I collect my refund from Strubenvalley or Woodmead branch. The appliances supervisor then calls Strubensvalley to make the arrangement, guess what? the phone just rang at Strubensvalley branch as well with no reply. So that number may also not be working. Now I have to spend another weekend with a broken fridge. I am mad, I am frustrated because it took me over 2 weeks to get the matter sorted and even after over 2 weeks the matter is still not finalised. I must wait for Monday, 02 June for them to collect the fridge and only then will I be able to get my refund. This is a waste of my resources, time and money. How does a company so big not sort out their telephone systems for their customers? Clearly we do not matter much, they do not want us to bother them....I am done with Makro, especially the Riversands branch.
