Lack of feedback

The app was revoked without prior warning or notification. I had a voucher available on the app following months of spending my money on this brand and now I can’t access it because the app is no longer active. I am basically being shown the middle finger time and time again as I have lodged a complaint through their contact centre, visited the Centurion Lifestyle and also sent multiple emails to a consultant by the name of Barry van Rheede. My query is still unresolved and they have ceased to provide any feedback. The last correspondence received was from Barry van Rheede stating that the voucher is still available and the restaurant should allow me to use it. He also promised to urgently address the matter with the restaurant after I had informed him of my intention to lodge a complaint with Ombudsman.
