Bad attitude from management

I am sick at the moment, so after I went to the dr I stopped at Dischem (Jean Crossing) to get my medication. (27July) My mother had a click and collect order that was already paid for yesterday afternoon (26 July), but they said it was still an outstanding amount to be paid. The manager (didn't get his name, big white man with red hair) assisted my mother as they were out of stock on one of her items. He gave a refund and said that I will be able to pay for my medication once the online order is completed.

Now I am sick with stomach flu, so my ideal afternoon is not spending it in Dischem waiting, so as soon as that transaction was completed, I went to pay for my medication. The system still showed that her medication needs to be paid. When the cashier (he was very friendly and helpful by the way) went to chat with the manager, he said that we are confusing the system by doing the transactions so close to each other. We should've waited longer (again, I am sick with stomach flu and all I wanted was my medication to feel better and go home). He was absolutely NO HELP and very arrogant.

So am I supposed to schedule my illness and only get my medication a day later just because their system is ****? Very unprofessional remarks from the management. Had to spend an additional 15 min to sort it out after I felt like puking on their floor at least 3 times.

Not the first time we experienced bad service from Jean Crossing. First time my mother tried the click and collect, they charged her R110 for a shampoo that was not in stock. They didn't even inform her. When we told them it was not in the bag they spent 20 minutes running around the store only to tell us that it's out of stock.

You do not treat customers that are ill with such arrogance and blame them for doing two transactions so close together. I will definitely not recommend Jean Crossings Dischem to anyone
