Xenophobic manageress in Virgin Active Sandton CBD

I'm extremely dissatisfied with the xenophobic attitude of the manageress named Mpho at the Virgin Active Sandton CBD. She's very rude and disrespectful to black foreigners yet treats white members with the utmost respect. This is not the sort of service I'm expecting from such a reputable company, it's unacceptable that this calibre of people are employed by Virgin Active.
