Bad service

You must train your staff customer service ..i was at Jet George 5 mins ago ...a very rude Cashier woth no name tag ..here is the thing..i bought white casual shoes at Jet garden route so as i was in town i decoded to return the shoes in town as the size was small ....so i went in firstly the cashier was just standing there pretending not to see me she let me stand there for 2mins while she was doing nothing just writing on the paper atleast she could have asked me to wait she will assist if she was busy but when she called to say i must come i saw she was just wring the papers so she could have assisted and then continues later to write her papers ...secondly i said to her am here to return her response was can i give a gift card i said no i want cash then she said go and come back later ...atleast she could have respected me as a customer as am using a transport to come to town so she should have apologised and ask if i can wait as she does not have cash in her till..instead she just said COME BACK LATER i then saw another customer i asked him if he was going to buy cash he said yes i said to her here is the customer his buying cash ...she said again come back later shouting at me .....i stood there because there was no way i could go home and come back later using a transport ........ u know when she was doing my return she started shouting at me about the price tag and i must read terms and condition at the back of the sleep and if you have camera you can see when she was giving my money she just pushed it infront of me ...am so dissapointed with the service you Jet give to us as customers ....i just stood there and said nothing then i took my money and left but telling myself i will mever buy anything from jet
