Here’s the concern about this review.
I was happy with the free version
So that would generally mean that the review of the version here would be 4 or 5 stars. But that’s not what you are reviewing, you are reviewing your experience with this plugin author regarding the commercial version and commercial support.
That’s outside of the scope of this review section here. These forums do not support commercial products.
You don’t have to update your review if you don’t want to but this whole conversation of yours needs to happen between you and the author elsewhere. Your issue isn’t with the plugin hosted here it’s with your commercial transaction outside of these forums.

If the plugin author attempted to support his customers here then at a minimum that author would get a shoulder tap and told “Please don’t do that here”.
