Local 6 News is reporting a troubling item.
Several Web sites will sell the last 100 phone numbers you have dialed to anyone who knows your phone number.
The report found that sites like Locate Cell will sell the private phone numbers for about $100.
Once the fee is paid on the Web sites, anyone can get access to the phone numbers, including bank, doctor and work numbers, Local 6 News reported.
