Horrible Service from Makro

I ordered a fridge beginning of July 2025, the fridge was delivered on the 12th of July 2025 but it was an incorrect product, it was not what I ordered & it cost less than what I paid. I logged a return ticket same day, I kept calling and sending emails with no reply, I kept calling until they collected the fridge on the 27th of July, I keep calling the customer service to ask when am I going to receive the correct fridge, they keep promising to call me back, when you call the head office no one answers the phone, when I send emails they don't reply back to me. I asked for a refund but nothing has been done, it has been over a month now. Makro's service is HORRIBLE! I send emails to *** but no one is helping me
