The call service which confirms your appointment the day before actually is of no use if you run late. This happened to me last week: I texted back that I was going to be late and I realised too late that the beautician had not been informed. As a result I did go in late and couldn't be seen. That is a massive issue if the booking service does not keep both sides of the conversation informed.
