Received a number of calls from someone claiming to be from Nationwide Mediation services indicating they are an arbitration officers for a firm planning to file suit at the XXXX County court. They will not divulge the original creditor and have called various family members whom I have n't spoken to or seen in several years. They continue to call and when I return the call the number is either busy or does n't connect. I have received no mail or certified mailings or summons or have been served at my residence or business.
