Bad service by pharmacist

Good day I am reaching out through this email to express my dissatisfaction with the service I received yesterday at Clicks Mafikeng Mall, where the pharmacist refused to assist me without the Clicks card. I visited to obtain medication for my son, and upon arrival, I greeted the lady at the counter. I presented my medical aid card document to her. She then requested a Clicks card; I explained that I did not possess the physical card but assured her that entering the medical aid number would reveal the information in the system. She outright refused to do so, insisting that she needed the Clicks card since it is a Clicks store, and her demeanour was quite unfriendly. She did not communicate with me in a courteous manner, which led me to leave the counter and return home without the medication simply because I lacked the physical Clicks card. My concern is whether individuals without a Clicks card are entirely denied assistance? I was incredibly frustrated, as her behavior significantly impacted my day. Although I did not catch her name, I can describe her or identify her if needed. I would greatly appreciate your prompt response regarding this issue. Regards, Palesa
