Two readings of the same reviews
Trustpilot’s own automated summary of this company’s reviews reads as predominantly positive. Our classifier, reading the review text in our recent window, judged 24% of those reviews to be complaints — most often support unhelpful. Both are automated readings of the same public reviews; they weigh them differently.
