Rude and disrespectful staff at Menlyn branch

Good day, I phoned your Menlyn branch the 2nd of March to make an appointment for a make-up session on that day. I was informed by Charmaine Cooper that Renier will call me back to confirm the time of the appointment. An hour later, I had to call the store again to hear if they were able to help me - Charmaine notified me that Renier will call me back in 6 minutes. Another hour went by and nothing. I drove to the branch and I was very rudely informed that they are too busy to help me. There was one client in-store and 4 employees. My call was not returned after phoning twice. Both Renier and Charmaine had a disrespectful attitude and were extremely rude. I would highly suggest that action be taken against such customer service as it tarnishes the brand's image. Urban Decay is an international brand and it would be a shame to see them go under in South Africa because of rude and disrespectful employees. I trust I will receive feedback on how this matter has been escalated and handled. Thank you
