Booked on Treatwell and arrived promptly for my reservation, only to be told that their ‘booking system doesn’t update on Treatwell’ and they were unable to fit me in at all - pretty poor when the issue was not my fault. What’s the point on being on Treatwell if you can’t uphold reservations made using it. I won’t be returning. Still to have it acknowledged in app that my booking was cancelled on their side too.
