Rude phone operatot

I spoke to a Khensani Masangwane based in Centurion. who literally told me I have a attitude problem when I expressed my frustration. I brought it to her attention that I am calling from a Work phone she still showed no sense of urgency to the matter, to top it all off when I asked who her manager is she cut the call on my ear. I am so irate and I do not think that an establishment as big as you should be having employees who are comfortable with undermining their client, I wish to take my business elsewhere and based on the level of her customer service I will never use or recommend any Sanlam product.
