What do you do when you find out the Manager ****?

My complaint centres around the allocation of the Studio. I understand that certain staff are contracted to come in and perform certain activities i.e. Yoga. Pilates etc. These are pre -allocated and in the case of the Meyersdaal club are sacrosanct in that you cannot enter the studio while the class is in progress. So I plan to come to gym when these finish. However what do you do when these classes run over evey week. You can see the instructor and you point out she is abusing her priveleage of timeand she ignores you? I have had this issue with her for at least 6 months. It all boiled up last week as I entered and put my stuff down in the corner when she ran over time. Bottom line first instructor then one particular student confronted me and abused me verbally. I took this up with Claudio and he appeared sympathetic and promised to chat with her. I am not the only person who has to wait and feel it is unfair to abuse the allocated time. I felt like the instructor was lietrally giving me the finger, weekly. This week I have found out that, a) he did not speak to her - this is what she told me and b) he has added 15 minutes to her class. So it seems I am a lesser member? Really?
