Disappointed potential client

I just spoke to a Popi from Bonita's medical fund. She was very impatient and unprofessional with me. She started speaking in her nominated language from the onset assuming I would understand probably because of my names , she seemed so annoyed by me and my questions. When I told her I didn't understand her language hence I was speaking in English with her so we could understand each other she continued, didn't even apologise and just asked me if she could continue with a stinking attitude. It's like she was never trained on telephone etiquette and basic human decency. I wouldn't trust Bonita's to be empathetic in my time of medical need with that kind of staff on the roster.I wouldn't hire her even to mop the floors.I was interested in a certain medical aid but it seems Bonita's is not interested in doing business with me.
