Disgusted with cold call from rude employee

I received a spam call after working hours by an employee named “Joe” who called me as a broker from the number *** selling insurance. I mentioned I was not interested and he asked why not and mentioned it was because I work with my insurer and would rather not disclose this as I did not want to continue the conversation further. The caller named Joe then persisted asking me why I’m afraid to tell him my employer and proceeded to attempt to belittle a potential client saying that I should listen to some insurance calls and learn about insurance before I say anything to him. I was taken aback and asked for his full name, to which he kept giving me my name back and refused to provide his name which I remembered his first name is Joe. Please go back and listen to this recording. It is appalling having to be harassed to be sold insurance
