Did the same thing to me while at work. I got aggregated and said some choice words. She then said they would not remove me unless I gave them my name even though she had given me my own phone number then hung up.
Left no message, when I tried to call the number back it says it is no longer a working number. I constantly get calls like this all day long. Really annoying, I wish someone could figure out how to stop them. I don't answer any calls on my phone that I don't recognize and I figure most people anymore don't but still really annoying when they call constantly.
