MBD harrasing me and not assisting

Msundo Zuma , contacted myself however she placed the call on hold . when she finally came onto the call she was laughing with her collegues , after a few seconds she said hello asked if i was Mr Pillay , i did not respond and asked why was she so unprofessional her answer was "It's a Call Centre"i asked to speak to her manager because she kept calling me Mr Pillay and insisting that i said I was Mr Pillay however Im a Govender Awe and said there are no managers available . I then called the call centre got through to Own located in JHB he then put me through Kumesh Chettial who was apparently a Line Manager ( Lies) he was rushing me on the call when i asked who was his manager and was not interested in helping . I have a clear credit record , I am not black listed however these guys keep calling and harrasing me. I want their CEO to contact me and apologise to me for their staffs poor services and for their so Called Manager Kumesh Chettial WOW he would never be a leader in my organisation so rude and arrogant .
