Rude Managers and loss on points

Visited the McDonalds in South Beach Durban in November 2021. They refused to let me scan my app to earn points. It seems they did not know what was happening. Simon and Noxolo are the rudest managers ever and the most unhelpful. I logged and complaint and received an SMS to say the case is resolved but till today it is not resolved. Noxolo and Simon called me to say there is nothing they can do for me to get me points. I did advise Simon he was there the day of the incident and it is not my fault they did not want to scan the app and i still want my points, he started screaming at me over the phone and was very rude. Noxolo was also shouting at me when she called. They both are unprofessional and should not be dealing with customers.
