Horrible customer experience

Yesterday I call at Multichoice call center Cape Town number worse experience ever as the lady that I spoke to was un professional and rude by the name of Mandy Janson if that is her correct name. I then requested to speak to her superior wich she puts me on hold over 20 minutes luckily I could her on the back ground as she was speaking about me with her colleagues in Afrikaans eventually the so called supervisor came to the line and he sounded as a agent as well by the name of Kerwin Jacobs. I asked him is this the way you speak or treat your customers with attitude that gives you a job he couldn't answer me then I requested the reference of the call wich I doubt the reference he gave me existed ***1/I44. This incident happened at 20:11pm last night
