It is a call out of Maumee/Toledo Ohio area. They are a debt collector for medical bills, I believe. They left a message and said they were HRRG. They don't have their name on the caller ID and when you call them, they don't answer with a company name. I called them using a blocked number and they finally said they were Phoenix Financial. They tried not to tell me who they were until I provided my contact information for verification.
