Worst Customer Service

I went to Totalsports Carlton Centre to cancel my lay buy, the disregard for customers at that store is at its highest. At first, I went to Eugene who was behind the till, he shouted and dismissed that he only helps customers with cards notwithstanding the fact that i was only cancelling a lay-buy. I proceeded to the next till and Tshepiso told me to wait for a few minutes as the "system" was down. I waited for a few minutes, and returned to her, she did not assist me but referred me to another teller who did not have a name tag. She told me to wait as well as she was to look for the item I lay buy'd. I waited until she found the item, but instead of assisting me, she assisted a customer who found me at the store, the said customer was buying a cellphone. I asked her who is assisting me, she said she is busy and someone else will assist me. She referred me to the fourth person, the guy also pretended like he is doing something on the computer, then passed the item and the slip to Tshepiso to assist, Tshepiso did not assist me but proceeded to give assistance to other customers. At this rate, I was irate and I asked them why are they taking me from one till to the other, no one seemed to care or even answer my questions. Another lady was called who finally assisted me. I was treated with disdain because I was cancelling lay buy, priority was given to those customers who were buying and not who came first. What I observed from this whole experience is that Totalsport does not treat customers who are exercising a right, to cancel a lay-buy, entrenched in the Consumer Protection Act fairly, instead priority is given to those who are only buying. This transaction was supposed to only take 10-15 minutes but I spend over an hour whilst being humiliated.
