Not to say that this type of harassment doesn't occur. There are other remedies available that appear not to have been explored. If you had proof, then a court order to stop the harassment could have been obtained. Violation of the court order will have more impact on police action than the filing of a complaint. The question remains, other than complaining what have you done to protect yourself?
[TELECOM Digest Editor's Note: What I did to protect myself is switch to a different telephone company; one that knows what *77 is used for and how to implement it so it works correctly, and overall it is a lot less expensive as well ($25 per month for a large package of features _plus_ unlimited local calling, _plus_ a hundred minutes of long distance calling per month). Admittedly, that solution is not available to everyone: SBC (and many other Bell telcos) tell many customers they are 'not eligible' for porting elsewhere.
And to get a 'court order', you generally have to have had the police involved first, to justify your need for a court order. The court does not hand them out willy-nilly to everyone who asks. PAT]
