Except that, the FDCPA DOES say that causing the phone to ring in a manner that would annoy or harass is a violation:
"15 USC 1692d
ß 806. Harassment or abuse
(5) Causing a telephone to ring or engaging any person
in telephone conversation repeatedly or continuously
with intent to annoy, abuse, or harass any
person at the called number."
If it were me, 4 times in an hour would most certainly be ANNOYING and I would consider it harassment !
They use auto-dialers.. and they will redial your number over and over and over until you pick up the phone. I had one CA who called my house 27 TIMES in ONE DAY - all in the space of about 2 hours. I have an answering machine program on my pc and it clearly shows every call and logs the time, date, the number calling AND WHO, if they haven't blocked it from Caller ID. I have sufficient evidence in those logs to nail their butts for violations - THAT is harassment !!
