So sorry to hear of your troubles. There are a lot of things you can
do, starting here:
What Should I Do If I've Become A Victim Of Identity Theft?
Link to all three Credit Reporting Bureaus are here.
Identity Theft: What to Do if It Happens to You
..."14. Phone service. Identity thieves often establish fraudulent
cell phone accounts, with monthly bills going unpaid. The imposter
might also have opened local and long distance telephone accounts. If
the imposter has obtained phone account(s) in your name, contact the
phone company for information on how to report the situation. The
steps that you take to clear your name with both the phone company and
credit bureaus are much the same as with credit card accounts
described above in steps one and three. In California, SBC-Pacific
Bell's fraud hotline is (877) 202-4558.
If your calling card has been stolen or there are fraudulent charges,
cancel it and open a new account. For your own phone accounts, add a
password that must be used any time your local, cell phone, and long
distance accounts are changed..."
Identity Theft Resources
I'd be particularly concerned about your SSN:
Identity Theft And Your Social Security Number
Document how you discovered this fraud, and the actions you are
taking, and send it to the people billing you for the charges, and to
ALL THREE Credit reporting bureaus. There's a link to all three above.
Also, call your local police department's non-emergency line and
report this, and get a case number. That will be helpful to make the
billings stop. Send a copy of this along with your letter to everyone
that you talk to about this.
If I can clarify anything for you, please ask for a clarification.
