Disappointed and frustrated 🥴

I placed an order of fridge and microwave on the 28th of March. On the 29th I called Makro to cancel a Fridge that I ordered because I got the second hand fridge and I was told my order has already been dispatched that I should tell the driver to return it. I haven't heard anything from Makro regarding my Microwave and I haven't received refund for the Fridge. On the 4th of April I called Makro to cancel the whole order since I was not been updated with the status of my order. To this day I haven't received my refund and there's no communication with regard to the status of my order. I am so disappointed and frustrated with Makro. I have spent a lot of airtime calling them with no assistance. I have been sending emails and WhatsApp but still no updates. I need my refund back Makro.
