Unknown numbers on your telephone bill?

My friend has been getting telephone bills with international calls on them - to Chile, Italy, etc etc. She hasn't made the calls. It is quite clear that someone is tapping into her lines and making the calls on our account. BT don't seem to be too bothered, have made her pay it and she's blocked all international calls. This has been over a period of some months.

Does anyone know how this is possible and what can be done?

If BT refuses to resolve the issue,file a complaint with state regulators,the state Attorney General and the Federal Communications Commission.

BT can give the information to you about who the numbers belong to.

If these calls originate from your friends telephone,some one is plugging in at the interface to the house or climbing the telephone pole.

It is also possible that they know your friend and are claiming to be him/her,but the phone co. is supposed to call your home phone for verification if the call does not originate from the home phone.

Also,there should be a phone number listed on the bills that show where the calls originated from.

Your friend can dispute the charges following the BT policy that should be printed somewhere in the phone bill,but it has to be done within 30 days and then BT has 60 days to respond and verify the charges.

Your friend may need to start keeping a record of all phone calls they make,especially long distance,showing the person and number they called. If there is a conflict about dates and calls,your friend will have a record to show that they couldn't make 2 phone calls at the same time from the same phone. Not sure how they can do this, but my advice would be to change her number?
