Terribly poor after-sales service from Makro!

I purchased a fridge online from Makro Woodmead in August 2017. The fridge stopped working on Friday, 06 April 2018. I contacted Makro HQ on next steps to get the fridge repaired/replaced as it is still under warranty. Makro HQ put me through to Makro Woodmead. I spoke to a lady who answered the phone after 5 mins of me holding on. She then told me to hold on again and I was on the line (holding on) for a further 10 mins and still nobody came onto the line! This is beyond frustrating, it is valuable time taken out of my work day to call Makro and be put on hold for lengthy periods of time. Could someone please assist urgently as I am left without a fully functional fridge and no way to address the matter with someone from Makro as I am constantly being placed on hold. Thanks!
