I had a terrible experience on this occasion. First, I was called by the venue and told they had double booked so instead could I reschedule for a Friday evening. Second, I arrived on the Friday evening and was told by the therapist I should have arrived 5 mins ahead of the stated time and that she had already packed up to go home. Third, I rebooked the appointment for a month later and arrived early to be told that my appointment had been moved from 3pm to 3.15pm without any prior notice
The clinic was closed, and nobody informed me about this. I called the clinic, and the lady on the phone was extremely rude. She insisted that my appointment was at 10:30, even though it was clearly scheduled for 10:00 in the app. She also seemed to blame me for the situation. In the end, the clinic was never open that day.
