I received a call from this number and what made me decide to look it up is their return number, 8778707255. I looked into it because what they were saying wasn't making any sense, they were looking to collect a debt that I owed for medical care that I received in which my bill is only $102 but they said I owed $607. I know my bill wasn't sent to collections because I just received something from that facility this week. I also know when it comes to medical debt they would go through a lawyers office and the courts, not a collections agency. What seemed even more off is when I searched the 877 number there is no company name and I read stories from other people stating that they refused any type of money order or check for payment, credit or debit only and refuse to give any type of address to their location... I deal with fraud on a daily bases so I can sense when I'm being lied to.
