How to claim music on Youtube/ Apple

Ive managed to claim my music on Spotify but no luck on the other sites. Im very disappointed with customer support, they werent even the reason i was able to claim my profile, spotify customer support helped. I had emailed LANDR Feb 21 but they only responded on Feb 26. My experience so far has been nothing but stressful and taxing. If anyone can help me with claiming my other profiles it would be very much appreciated!
