Contact Center with Very Poor Service, ***********, Rudeness, No listening skills and No phone Etiquettes

8th September time 12:34 I called *** I spoke to Nomvula Nkabinde who does not have listening skill, very rude, was arguing with me.My reason for calling I wanted to verify if the application fee was received as I can't find the upload proof of payment option. She called a manager while I was holding she didn't mute and could hear her saying I think I'm special....... When I asked the manager why is she saying that Halim said his rushing to a meeting he will call me back. At 13:06 he called me back from *** he was rushing me, didn't wanna attend to my complaint about his agent Nomvula as I wanted to know is that how they allow them to talk to client, we started arguing he then hanged up on me without my issue being resolved. I need someone professional who has phone Etiquettes to call me back to assisted.
