Incompetence is main feature in the store!

My mom an I went to Clicks pharmacy in Key West shopping centre last night on the 30th of August 2017, we bought a list of things including 2 items which were on special, (btw mt mom has a klubcard) the specials apply to cubcard owners only - so i know that we have one. The cashier who helped was un friendly and there was only 2 open at the time - we went there after work at +- 17:30. (There was many other people behind as at the time) the staff was in no hurry to help. When the cashier scannend the items and wanted us to pay we noted that the total amount was higher than we thought it would be. So we took a look after payment was made. And saw the amount was normal charged not the secial amount whice was on the rack with the items. The cashier then walked a litle faster than normal to get the wrong paper to scan, i went on my own to get the right price from the rack from where we got the items. After another long and dreadful wating I saw the other cashier was walking and holding a envelop with some money and giving it to the other one standing there. (At this point there was many employees which were doing nothing, standing around and looking verey bussy, and in the meantime the line of customers waiting was getting longer and longer behind us at the till.) After some time she took the clubcard to scan, with an irritable expresion on her face and worked even slower to continue to see if there was a mistake, the manager then had to use her keys to open something or over right someting. Then se wanted the credit card again to place the money on - that she made a mistake with the items on special, not us. My mom asked if they could give the money instead of reversing it back on the card, the one who was standing and looking pretty sead we must ask the other one who was standing next to our cashier, she answer was no we cant. Then my mom had to sign on two pieces of paper slips, for a mistake they did, she also wanted her name and contact detais - by this point we were very impatient and upset, they must vill in THERE name and contact details it was there fault in the first place. (The cashier gave no sorry or word other tan miss you must sign, ...your number miss, and slaming the credit card on the table before that.) The slip' time stamp was 17:53:21 (30Aug2017) and the cashier who helped us was Kgotatso (dont know the surname, or the other employees names) the items we bought that was wrongly scaned was clicks trim shake x2 (the special was on buying 2 for R166 instead we had to pay normal price of R200) this had happen more than once with items on special and the till not in sync with the new prices or cashiers not refreshing the system with new info.
