The Error: Another common billing error is the ghost product charge: a bill for something you did not order or never received.
Ghost product charges billing errors typically happen on bills that are not tallied right in front of you, but bills that are created by people unrelated to your shopping or service experience. Secretaries, catalog employees, and online buying sites are all common culprits for committing the ghost product charge billing error. It can include a charge for X-rays you never got at the doctor's office, protection plans you never asked for coverage with, and additional items that you did not click on to buy.
In many cases, unlike the double charge or incorrect charge where there is immediate physical proof, the ghost product charge billing erroris harder to deal with. It takes longer to track down whether certain services were or were not rendered, whether items were or were not sent, and whether you did or did not make those long distance phone calls from your hotel room.
How to Avoid It: There is little you can really do to prevent ghost product charges, as many of them are billing errors made far beyond your scope of control. The best thing you can do to protect yourself from paying for them is to review any and all bills, statements, and invoices line by line. If you see something, say something - call the customer service number, offer to return goods as proof, and refuse to accept charges for things you didn't buy. If employees are being stubborn, always feel free to invoke the right of calling the Better Business Bureau or the Chamber of Commerce for a little back-up.
Also, consider this: in this modern age, we trust computers, and therefore tend to trust most things as coming out of computers - like automatic bills, for instance - as being correct. However, it was the imperfect man who built the supposedly perfect computer, and that computer will make mistakes too. Just because you get an automated charge doesn't mean it is supposed to be there. Prepare to get on the phone, speak to the supervisor, and fight for your right not to pay for charges you didn't incur!
