Terrible service

I called sanlam this morning inquiring about an insurance that is deducting from the company's bank account every month. I needed to understand exactly what this policy is for? Lucinda January is the lady I spoke to, in the 10 minutes that I spoke to her, she laughed at me, made stupid comment and remarks. Then I requested to to speak to her supervisor, then she told me that the supervisor Marlene Lerm was in the bathroom, told her I would hold, but she wouldn't allow me. Then I asked for the supervisor's email address she told me that she didn't have one.
