Online refund.

I ordered a stove and canceled the order on the 6/04/2025 and as of this date 15/04/2025 I have not received any confirmation that the stove as been canceled or got my refund. I have been calling for 6 days and I keep getting the same answer "I will follow-up or it is still with the courier" I am struggling to get the refund from them aswell as a status update. I am at a stage of taking legal action against Makro
