Refund from Lewis

On the 27th November 2024, I bought a cupboard at Lewis stores in Engcobo. I waited until January 2025 to get it and I was told there is no stock. On the 11 January, when I wanted my refund to they said they don't have cash I must come on the 15th. I waited and no one called me or give me any update. On the 17th I was called and they said they don't have cash again. Around the 22nd, I called the head office which told me that they have sent my details to the agent. I am still waiting and no one is updating me. Very poor service, I want my money back because they failed to give me the cupboard that I paid for and are sending me from pillar to post.
