bad service and attitude

I am appaled at what happened today. I received a call from these people, I responded by saying that I am busy I cant talk. The consultant lady said "then why did you pick your phone" in a very annoyed tone. Hebanna. as if that was not enough, she kept calling me and kept silent. I really feel abused. Even now I received a call from her. Really what kind of petty unproffessional behaviour is that.
