Unprofessional

I went to Pep store thorntree soshanguve on the 22/03/2020 to buy Dino tissues which were on special,I asked one of the ladies who's working in this particular store she told me on their system the tissues were R10 more than the special price and if I don't want it I should leave, she was very rude and unprofessional, no name badge and didn't care or looked like she was on duty.
