Clicks pharmacy cradlestone worst service

I received the worst service ever at clicks pharmacy cradlestone. I went to them yesterday and the lady helping me told me my medical aid don't have funds with an attitude. Later yesterday I got an email that clicks claimed from my medical aid. I went to them again and the gentle man who helped me told me that it will be revised. I came back later and the same lady who helped me yesterday said my medical aid don't have funds, I tried to show her the emails I received and she shouted that everyone around heard her, she shouted saying you don't have funds so what must I do. She showed no respect at all and had no customer service at all. I could swear she was not Trained on customer service. She should be taught how to talk to every customer. It's not the first time this happened
