How to Protect Yourself and Save Money
Carefully review your telephone bill every month. Treat your telephone service
just like any other major consumer purchase. You should review your monthly
telephone bills just as closely as you review your monthly credit card and bank
statements.
Ask yourself the following questions as you review your telephone bills:
"What services were provided by the listed companies?"
"Does the bill include charges for calls I did not place and services I did not
authorize?"
"Are the rates charged by each company consistent with the rates that the
company quoted to me?"
Keep in mind that you may sometimes be billed for a call you placed or a service
you used -- but the description listed on your telephone bill for the call or
service may be unclear. If you don't know what service was provided for a charge
listed on your bill, ask the company that billed the charge to explain the
service provided before paying the bill.
