Bad customer service

Hi, You know when we(customers) go into retails stores we go there to purchase goods that we need,we go there to bring business into that certain store not to be verbally abused by your staff.I had the most horrible experience in pep store waterfall mall today,i was assisted by a very rude and ill mannered cashier.I have shopped at that store for the past 15years as it is the pep that is close to my house but after today i will never set my foot there.I left that store very disappointed.I got a pair of tekkies for my son which had a red sticker,when i got to the till the cashier told me that the tekkies don’t have a barcode therefore she can not sell them to me.i was very suprised as it was the first time i have heard that a customer cannot purchase an item because it has no barcore.I then asked her to get someone to come and assist her,she rep**** me with a bad attitude that the manager is busy receiving lots of boxes so i will have to wait for him.i asked her for her name as she was not wearing a name tag and she said her name was “***ton”.when i asked where is the manager’s assistant,she said the manager does not have an assistant.i then told her i do not like the bad attitude she has,she told me that i am the one with a bad attitude.eventually the manager came,and as i was busy explaining to him what had happed she kept on talking on the side and interrupting when i was not even speaking to her.I then realised that she has no respect whatsoever for her manager,no wonder she does not even respect customers.I asked the mananger what her name is and he told me her name is “Decorations”.so she looked at me in the eyes and gave me a false name.
