Remember folks, only legitimate businesses follow the do not call listing. These scams callers do not. It is pretty simple to figure out. If you are on the do not call list and they call you, you can bet it is a scam. Of course you could discuss it with your phone service provider. If you try to call them back you are generally informed that the number you are calling is no longer in service. You would think you provider could stop calls from phone numbers no longer in service. If you don't pay your bill they stop your phone from working right?
