Bad customer service from hell!

I have ordered a two plate oven stove at Makro on the 7th of March 2025. The courier guy came on the 12 of March 2025 to deliver the stove to me, only to find out that the stove was not the one that i had ordered and i did not accept it so the courier guy went back with it, i then immediately called the customer service to let.them know On the 14th an email was sent to me saying that they have received the stove back to them. I the called to let them to log a refund for me, which they confirmed they did and I should receive my money back within 7-14 days. Up until now i have been calling to check how is the refund process going but every time i call they say the information is not updated on their system and it’s not showing that the refund was processed. I am being told a different story every time i call them, i don’t even receive any feedback from them im the one who’s making an initiative to call and ask. I feel like i am being not assisted because im black, if it was a white person they would have assisted long time ago, and it seems like i will not be getting my money anytime soon!
