At least 5 classes that I know of are no longer offered and are still listed. At least I don't think they are offered as no one will contact me when I try to confirm.
Times for some classes are also wrong. There is no incentive for the instructor of Zumba to keep the classes up-to-date. I've sent emails and called Zumba and they say it is up to the instructor, and that they have no say in the matter. When I asked the person I was speaking to, to talk with a Supervisor.
She would not refer me. It's very frustrating to line up a schedule of classes, when one never knows if the classes are still in existence.
