Decofurn refusing to refund the customer

I bought a stand on the 25 August 2025 and I paid for it. I was told they will let me know when they receive it. Since then the was no communication, till I decided to go there today 11 September 2025 to tell them I don't need the stand anymore, only to be told that the stand is available and already assembled. I told them am not interested anymore only to be gave a form to fill in my banking detail. I was then told that they are waiting for the email from the regional manager. The regional manager then sent the email that we have to take stand. So I don't understand why are they forcing me to take something I don't want anymore. I paid for the assemble so I just need my money back
