Pretty much the same.  They call, leave no message.

have been getting numerous calls (beginning at 8am) from this number...no messages left!

They called 12-14 times per day over the course of a week.  We answered once or twice, and no one would answer on the other end.  After answering a couple of times we simply let the answering machine pick it up: no messages were ever left.

These calls have been comming for a month and a half. These jerks call atleast 15 times a day sometimes 2x a week. They claim to be AT&T claiming you owe something, and when you ask to speak to a supervisor, they give you a # to call. The number is actually to a phone sex line.
