this is another number for a DEBT Collector aka HRRG (healthcare recovery resource group) ARS
( accounts recovery services) leaves no messages , call back tell you to wait for next rep..BTW this give them time to retrieve/ copy your phone number and pull up your account information , send a do not call letter to stop the calls, you can find their mailing office in your state by doing a business license search, that will also tell who the "managers are"
