insulted

I so shocked how Rude Call centre Agent are, I received a call from VVM debt collectors about my Trueworths account and I advice the Agent that can she give me a call at 12 mid day because I am not able to talk at that point of time we she arrogantly says no why at 12 u I have already told her why and she starts to disrespect and suddenly told me that i am stupid, my phone is an android Phone and it Records calls and I am gonna take this up to the highest level and I wanna publish this voice recording, me being outstanding on my account don't give any call centre a right to swear or insult me, I made calls before to the company for arrangements and I failed but now they insulting me. Fortunately I also have my own recording. I want this to be dealt with as soon as possible. She Said her surname I Miss Khuzwayo.
