[US] Voice mail left, is this a scam?

A voicemail was left from California regarding document compliance and certification for a reactivation action due to a breach of contract associated with a specific case file number. The message stated that the file was in their fraud department and referenced potential loan actions, requiring the recipient to contact the mediation department immediately at a given phone number. It warned that failure to respond would lead to adverse decisions being made on the recipient's behalf.
