it's not first time, they have mentioned all different time for sessions but you may go planned and they have no class. the trainer says we originally never had any class, the watchman says there is no class ever at that time. they have faked timings. and they don't care if you go sparing your time. this has happened several times with me. my whole workout plan messed up for those many days. please go at a place where they don't cancel it on last moment. don't rely on them. have some home set up where they deal with casual attitude.
