Bad Service at IStore Menlyn Park

Good Evening. I am totally disappointed by the level service I recieved a few days ago by the name of Marcel or whatsoever, a consultant and his manager at the I store in Menlyn Park. The consultant gave me an attitude when I tried to purchase a device with them, cause initially I went to Telkom and they told me that they are out of stock that I should go to the Istore, I did exactly that and I recieved some bad ass athitude, I may have not the proper documentation but why didn’t the customer go an extramile to contact Telkom and tell them that they should explain to customers proper rules? Instead he was unapologetic and giving me attitude. Fast forward today, I went to lay a complaint to the branch and I was told that in order for me to get an apology he needs to hear both sides of the story. He wasn’t even remorseful and they dismissed me just like that unapologetically! Saying I’m too loud. What happened to service excellence? What I experienced is tedious, it positions the brand Apple in a negative light.... I am expecting quality devices and quality staff from Apple, they were not willing to apologize, I am so disappointed!
