Unfortunately the treatment did not happen, but the whole behaviour wasn't good, nor right.
When I arrived nobody was in, the lady didn't know about my booking and was kind of blaming Treatwell. Not great as I know how great and reliable Treatwell is. Then she decided to come but cancelled right after she found out I am booked on the deal which was obviously officially agreed between Treatwell and herself, but she didn't like it.
As I sais, sadly a total waste of my time.
