I have had a guy say "i want this to be a 5 star experience" and it was not. His apartment was messy, stunk like weed and his photos were real but overly flattering. He did put effort in, and I could see he was trying. If pressed I would have given him a 3 or 4 star review for that. Suffice to say, I did not post that review. I just left it be. He wasn't a bad guy, and I did not want to leave a small business a bad review. He just was not what I would give 5 stars.
Unless you want to give constructive feedback privately, I think in these cases @RyanDean the old saying 'no reply is a reply' is appropriate.
I must confess - when I am looking at a provider and they have one or two less than stellar reviews - I do go and read those reviews, rather than the 5 star ones. I do it with hotels as well. I also check out who left the review and see if this is something they do often, or is it a one off. If they have lots of reviews and only one bad one, I will proceed with caution. Two and I keep looking.
