I receive several calls from this number, never leaves a message. Once while expecting a call from the hospital to learn about test results I blindly answered the phone. The caller ID says the call originated in Collinsville OK yet the caller had a heavy accent and you could hear multiple calls going on in the back ground. Asked caller politely to hang up as I was waiting for an important call. Caller then began to say that they were far more important than any other call I was expecting, and that my failure to pay them for this debt reflected that. I thanked them and asked them to please send notice of the debt with my signature showing that I owed them for this debt. They refuse to do this and I then stated since they refuse to send information requested, then this debt is considered paid by refusal.
