Super bad service

I have phoned the Chicken Licken at East Rand mall, and for the 1st time ever have I received such a shocking and disrespectful service, my order was placed in time and properly captured and it was to be delivered, after an hour of no receiving my order I decided to follow up and spoke to Joseph who was very helpful, however in the background a boy named Noah called me a **** and says I didn't place an order and he was the one who took my order and didn't process it, the fact that he doesn't know me and he didn't process my order and still have the nerve to call me a **** and thinking I didn't understand Zulu just because I spoke in English, it is unacceptable an very unprofessional as I'm a loyal client and this has never occurred to me, the least he could do was own up and apologies as I understand we human and we forget, not all me a ****, I'm very disappointed with this service.
