Absolute farce. Wanted to rebook. Had text saying you could do so an hour beforehand, appt was due at 4. Rang up repeatedly all day to Treatwell number. No reply. Left two voice Mail messages. No reply. Downloaded the app,to rebook, wasnt able to add didn't work. Emailed. No reply. Went anyway when appointment was due, and it was shut. Worst customer experience I've ever known. Would have given zero stars if I could.
