Well, there are audios for both removal of entities and spells, so I guess not much to discuss there 
If they aren’t available to you now, one thing you can do is call upon benevolent entities to help you, archangel Michael being one of them (Sammy described in detail some time ago how to go about this, I’ll try to find it) 
Also, when you raise your personal vibration most of those beings stop being a match to you, especially if they were “sent” by someone else.
Edit: I can’t remember in what thread that post was, but in the meantime, you might benefit by checking out these
