The BBB complaints list is a glorified internet post. It's not keeping a business any more honest than posting a review on Google or Yelp.
Yelp reviews, TripAdvisor, Google reviews, yes.
And as honestly never crossed my mind to check with BBB about anything.
But I haven't done any major purchasing like with property, land, or similar.
Don't know how that works. It's Poland, approximately nobody here even used Twitter, nor do they use X - and yet, businesses big and small seem super sensitive to that.
Complete with undeserved reputability and "pay to remove" system to extract $ on the business facing side.
I do think Mindless2112's experience is common with larger businesses, making the BBB potentially more effective in those cases than online review sites like Google or Yelp. Also, do those sites send complaint letters? I don't know.
