Apple Deleted a song I purchased - not available on itunes store anymore, not in my hidden purchases

I purchased the song Golden by Vibe Tracks on 17 December 2021. I wanted to listen to it a few weeks ago and found it was deleted from my library. I checked the itunes store and the song is no longer listed. The song is not available for re-download. It is not in my hidden purchases. I have contacted Apple twice and have received no response. I would like a refund or the song to be restored to my library.
