RUDE AGENT

I just had the worse terrible shocking service , I called in to the dispute department for a follow up, The agent I spoke to demanded a "PLEASE FROM ME " spoke to me like I am a illiterate, I am sure the respect from Fnb is as per one earnings right ? Because I spoke to a Team Leader by the name of Kgomotso from the same department , wow she went on as to speaking venac , she was so rude to me she ended up hanging up the call. There is no way on Earth I am going to be disrespected in that way , I will personally deal with this behavior.
