I had an outstanding balance of around $60 for a hospital visit when i had first started receiving these calls, leading me to believe that this is a third-party collection agency. But each time I answer the phone, there is no reply - only the sounds of people talking in the background. Although the hospital balance was long-since taken care of, this company(?) still calls me daily - and since they do not choose to either speak or leave a voicemail, I can only presume that they are calling merely to meet a quota.
