That is extremely peculiar. Foremen are field supervisors who supervisor the field techs out around the neighborhoods. When you call into tech support you an online tech support agent. They are not supervised by foremen, they have regular office supervisors. This is extremely odd to me too because its not like you were asking to speak to his direct supervisor, you were trying to speak with the field supervisor so there's no reason for the agent to get mad. I do apologize for the treatment you received because in any situation the online rep should not have gotten angry or hostile like that.
I, too, am having issues with the install of my new verizon services (landline & dsl bundle).
