I keep receiving calls from a company called HRRG and they ask me to verify my identity to continue the call. I tell them I 'm not giving that info out to a company I 'm not familiar with. They keep calling and telling me that I owe a number different than the medical provider that claims by insurance did n't cover their er visit. They 're somewhat rude and they hang up on me. I 've asked them repeatedly to stop calling me and it continues.
