Bathu SA customer service is appaling

I bought a pair of shoes on the 23rd October and a two days later received my order, but they had delivered the incorrect shoe size I then contacted them and requested info and sent the shoes back on the 25 and since then I have so many issues with me. They first claimed to have not received the shoes after send them the waybill number for tracking. Then just went quiet on me until I made contact on all social media platforms requesting a refund and that's when they only made contact with me. We are now in December and I still have not received my money. Bathu has the worst service ever and no one wants to account for anything. I want my money back because at this rate it seems like they are hoping I forget that I ever placed an order with them and they did not deliver yet took my money.
