Your fault, but don't even apologise

So on the 24 of December I went to buy my husband some shoes and to pay his account. 1st I pay the account and then I wanted the one pair to be paid against the account and the other I wanted to pay cash. So when the transaction on the card was almost finish Nomsa explained to me that I can't buy on my husband account cause his not present. I laughed and said atleast I can pay it. So I ask her to still buy the one pair on my bank card and pay the other on cash as I needed the change. So the price she charged for the shoes then was wrong. The price on the tag says R129 and she charged me R159. When I point it out she grabs the other pair from my hands and starts ringing it up. I ask her to fix the other on and got a rep**** I WILL DO IT AFTER THIS. In the mean while Bella from Estee got there. I'm not sure who she is but she helped Nomsa to credit the shoes that was charged on the account the first time. So not one of them apologised for their mistake and gave ME the bad attitude. What is bad is that this is not the first time I heard of this bad service given at Edgars Klerksdorp.
