I feel you have an extremely biased and/or myopic view if I may say.
Many of us (including me) have personal experience of dealing with tutors and it is not the same as dealing with teachers.
When a parent is looking for a tutor for their child, they can only go by the reviews they can find, if they can even find any.
You may go to parent- teacher meeting where your child gets glowing praise from their school teachers but you may not have a clear understanding (because you are NOT a teacher) of whether your child is doing well in that school pool only, or whether your child might be doing well enough to attempt a challenging exam that will allow them entry via an exam like the 11+ into a selectively academic school.
Since you don't have the knowledge to assess this accurately, many parents (me included) then start looking at tutors because as tutors who specialise in getting kids through exams like 11+ I was assuming they have some sort of bench mark based on past experience, performance of their past cohorts and also access to historical data that I as a parent do not have any visibility of.
I have no way to assess the tutors other than the reviews from other parents which will mostly be on the Internet and/or word of mouth.
So yes, reviews are extremely important.
Tutoring is bloody expensive and also invasive in that it takes a lot of time - either after school late into the evening or almost every Saturday morning even in half terms. Given that financial cost and time sacrifice then YES I absolutely expect a professional service - transparency, honest and excellent communication. If I raise concerns or questions I expect them to be answered fully and promptly. If my child is absolutely not going to make it then it's imperative that there is a sufficient level of honesty between me and the tutor to be able to tell me that.
I am not saying that is what is happening here with @Booyou123 but I do think the way you phrased your post was extremely one sided without much thought to what the @Booyou123 would have been (rightly so) expecting.
You can't take so much money off people and then just be really vague in communication and then go absolutely mental when you have had a bad review. Rather than banging on the OP's door at night time that tutor, if professional, should have set up a meeting to discuss OP's concerns in detail and I am sure middle ground would have been achieved.
If the Tutor had responded comprehensively in the first place the OP may not have been compelled to leave a negative review.
A lot of people (like me) who organise tutoring for our kids are not rich. Everyone is going on about how the Tutor may be facing financial difficulties; no one has said anything about the amount of money @Booyou123 would have forked out for a service that she does not feel that she received.
Also, this part of your post is nonsense @Slightyamusedandsilly to me.
It's not a lack of awareness to understand (from personal experience in independent schools) that the vast majority of parents think if they pay big bucks that it guarantees top grades. They absolutely do expect that."
A lot of people like to say this sort of thing but in my experience it's completely untrue in a lot of cases. We went independent because our local state school was in special measures for racism and I didn't want my kinds being beaten up for the colour of their skin. The only other choice was an independent due to how the catchment areas in my area fall. We could not afford to sell up and buy in a better area. We are not rich by any means. We are both academic and professional but we did not EXPECT certain results just because we paid some fees. Others in my children's class chose the school for other reasons - SEN, family ties, etc.
I hate your sweeping generalisation that fee paying parents are demanding, uniformed parents who think they can buy better grades.
Just like all other parents, we just want what is best for our kids. There is no way we are just paying for better grades. For you info, my 2 DDs have had very different academic outcomes. There is no money we could have earned that could have changed their natural abilities.
