Your account could be restricted for either a copyright strike against your content, or a music service has notified us of "fraudulent streaming activity" which is when your streams or views were manipulated using bots or artificial listener accounts.
Reviewing these matters takes time. If your account has received a copyright strike the only way resolve the matter is to have the claimant retract their claim directly with the music service where they filed the claim. If your account is restricted to do "fraudulent streaming activity", your account/content cannot be re-instated. This decision is not SongCast's but rather the decision of the music services such as Apple, Spotify, etc.
