Bill Collector for unknown company or a scammer, either way, you want my name when you have called me? If you don't know whom your calling you shouldn't call. When your caller ID only gives a number but no business name and then you don't identify your company name when you call, do not be surprised when I refuse to identify myself to your agent. I did not ask you to intrude into my life on a telephone line that I pay for. Have a nice day..Click!
