Help From The Telephone Company
If you have used the techniques suggested on this page, and you still keep getting annoying calls (apparently from the same source), call the telephone company’s business office at 1-800-310-2355. They have representatives trained to help you.
One thing their representatives might suggest is that you keep a record of such calls. The information you record there might give you valuable clues to the identity of the caller, and could help both the telephone company and the police establish a pattern that could help identify the source of the calls.
Other things they may suggest are Caller ID, Call Return, or a "phone trap" placed on your line.

If you are the victim of a threatening or annoying call crime, you may report it to the El Cerrito Police Department so that it may be investigated. You can call our dispatch number, 24 hours a day (510-237-3233) and a patrol officer will be dispatched to assist you.
