Makro does not want to refund me

I ordered a Chimney First week of Feb 2025 and i got a microwave delivery, i logged a return where Makro came and picked the Microwave within 3 days, i then followed up about my refund/delivery of what i had ordered and makro stated that they only refund me. To date i have not received any refund, its been close to 2 months, i call them daily and they keep saying they escalating to Finance department. I am so disappointed for such a huge Brand and the poor delivery. Please assist me so that Makro can pay my refund
