Click’s Sandton City

I was turned away at Clicks Sandton City for my vitality assessment because when I book on their app it wasn’t showing, so I drive to Clicks. Only to be told about other people that were there before me who had similar issue? But I’m here now so why am I told to go home coz I’ll be booked in the next hour? So I must drive back again after being physically there? Why can’t you assist me now?
