When having a conversation with Ms Yee, at some point I was not clear what she had said and requested her again to repeat for the second time. She sounded aggitated while explaining to me and thus raised her voice on me, which i felt that she is not being professional and the way she said is appropriate. She was not able to restrained her anger hence I feel disappointed for such behaviour. I do hope at your end to be able to educate your staff to better handle things proper.
