Bad Store Manager - McDonald's Capricorn

I placed a order on the Mc Donald's app for delivery at 19h37, 20min later I received a message my order has been canceled, a few minutes later I receive another message to say my order has been placed with Uber Eats. It's now been more than a 1hr and I drive to the store instead, get to the store I inform the manager of my situation. I asked her can you you rather give me my order I'm here to collect the order instead. This stubborn manager by the name of Phindi insists that she can see the oder on the system but it was not allocated to Capricorn store. I continue to tell her thats Mc Donald's internal issue, give my order, you have my money. She continues to let me wait for another 45mins in her store. She did not even apologize, she disappears into the back area on the telephone with their head office. I eventually walked out of the store 50mins later without my order and McDonald's has my money! Phindi is a manager but has no customer service what so ever. I am still waiting on a response from McDonald's to speak to Phindi's Manager. Phindi at Mc Donald's Capricorn has no customer service at all, send her for customer service training Mc Donald's South Africa.
