Was told I will not get helped if I do not issue my ID

I went to get my daughters medicine at the Middelburg Mall Clicks Pharmacy. I have gone cardless for over a year. I have a clicks card on my phone and my bank card so I do not carry my wallet with me. As I get to the counter and give the lady my phone she tells me I need your ID. I told her I do not have it with me. She told me she will not help me if I do not provide a ID or my Medical cars. I have not issued a ID or my Medical aid card as I have been getting my blood pressure and pain medicine at this branch for more than a year. I have never been told and treated like this. This is poor service and you do not want some people's business
