When writers take your request, which they do for free and on their own time, it is a gift. This is not a service nor a business so there should be no complaints on the end result for something you paid nothing for.
And when you send in your suggestions/list, it is up to the writer to interpret your ask the best they can and to their comfort level. They take time out of their busy schedule we call life (work, kids, cleaning, errands, ect….) and write something specific for you. When you come back and say they didn’t get a specific thing to your liking or you didn’t think it was up to par, it is a slap in the face to the writer plan and simple. Trying to give criticism or explain why you didn’t think it was right, is rude and being unappreciative. 
While they appreciate the love and asks, they do not owe you anything. They have the right to delete any request in our box if we don’t feel like doing it or don’t like the content laid out. You are not owed perfection, you are owed nothing. If your ask is completed, like and share and give the writer thanks for taking the time for you. There should be no other response. End of story.
