Very bad service

I went to clicks diepkloof square, to buy some meds the pharmacist told discovery is not operational on Sundays as they are updating their system,I asked many times if he is sure cos it was not the 1st time m buying on a Sunday, I told him to wake up as he wasted my time he was supposed to tell me that as soon as I gave him my discovery card. To my surprised On my way back home he called n said its been authorization. I said to him you have time for jokes ,he said to me I must not be rude to him he threatened me by saying he will cancel my things and I will go n buy somewhere ,I came and report to manager on duty Daniel Selepe he **** and deny what he said to me. I told the pharmacist Chadiba Mangena m gonna report him he said its fine I can go ahead, he didn't even Apologize .
