They have been calling for a week, 3 or 4 times per day. Maybe more since I am not at home all the time.  These people are disrupting the peace of my home and invading our space. Why not write?

This number calls me EVERY SINGLE DAY, several times a day.  They never leave a message.  I know I owe some bills but if they don't identify themselves . . .
I just have them as DO NOT ANSWER.  They just keep on calling.

I need to identify this called

VISA, YOU ARE PAST DUE...

This number leads to a credit card company. I don't know which one, as the recording didn't say.
