Horrible and disrespectful undermining service!!!

Very sad! The lady shouted at me and chased me out. I asked, do you use a medical aid, she said yes but give me a physical card and your ID, i then gave my ID and said i have a digital card, she said email it, as i was doing that, i asked, what is the next step and the process to select a frame plus eye test, she said she must 1st get the medical aid to approve the give me a bill to sign, i then asked, what bill should you give me yet i have not selected anything, she then said i must be billed 1st so that she is sure that i am not there to waste her time. I told her thats not correct on my side then she said talk to my manager (i then learned later that the “manager” is the owner of the branch) the manager didn't know what to say as already the lady was shouting at me and chasing me away. They have EXTREMELY HORRIBLE SERVICE!!!
