Unfortunately SoundCloud do not have the technical means of reverting, or adjusting, play counts. This is because unlike fake likes, follows or reposts these plays are not actioned by a specific SoundCloud account/user that can be removed. You can delete and re-upload a track to refresh the play count, but keep in mind this means all Likes, Comments and Re-posts will also be lost.
To prevent further plays being attracted to your track, you can try changing the track URL for a small time. Plays are often bought for specific track links and this may divert them.
Hope this helps
