A Problem Solvers investigation has discovered that 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.

The Web sites are not illegal, according to the report.

If you believe someone has found your private information through a cell phone number, you are urged to contact the Florida Attorney General's Office.
