Yes. There are many ways that a call can violate the law. Some examples include, but are not limited to situations where the debt collector calls too early in the morning or too late at night, where the debt collector threatens you, harasses you, where they fail to disclose that they are a debt collector, where they fail to provide the caller’s identity, where they call too often, where they use profanity, where they mislead you, where they claim that you have committed a crime. There are many types of violations and each call must be analyzed carefully. It is important to save voice messages and if legal within your state, to record phone calls.
