Terrible customer service at Virgin Active Claremont

Visiting from Dubai and Zanzibar, we obtained day passes from our Vitality apps which was approved on the app. When we got to the gym - the young staff member there was friendly enough but had to call her supervisor to assist us. The guy, so called supervisor, goes by name Zack. Extremely rude and with terrible demeanor and zero customer service mannerisms. He said that their system does not allow Vitality passes when there is a QR code for Vitality passes right on the reception desk. When I told him that, he laughed and said that it was a mistake and shouldn't have been there. He then proceeded to remove the QR code from the counter and refused to assist us further and then just moved on to do something else. Needless to say, we will not be visiting Virgin Active again and will be reporting the incident to Discovery as well.
