Makro refuses to process Refund

Makro has the worst service I think I’ve ever experienced in my life! Their post sale after care is terrible. They delivered a damaged & defective fridge to me 3 weeks ago. I had to beg and wait days before they finally collected the damaged one. I was advised in 2-3 days I would receive a replacement. Only last week, do they call and say “ oh by the way, we do not have stock, we will refund you in 2-3 days. It has now been a week and every time I call I am Being told the matter has been escalated. I don’t have a fridge for 3 weeks now and I have incurred so many additional costs because of this. They won’t refund me so I can not go to another store and purchase it. I have contacted my lawyer and the ombudsman man, so I expect my refund paid back with rebate interest they have gained from MY MONEY sitting in their bank account.
