Received a phone call from an unknown number leaving me a message to call back XXXX. I called back. They spoke of a debt that was from XX/XX/XXXX -XX/XX/XXXX? I live in Colorado statue is 6 years. They said that there will be a court hearing on XXXX XXXX. I looked it up and I do not see it on the docket. They also said that the sheriff 's department would be serving me. I called the sheriff 's department and they do not have a record. When I call the number I speak to the same person over and over never identifying themselves.They are demanding XXXX payment via credit card or money order by tomorrow to stop the court process. But as a law office they do n't have to tell me anything they guy was willing to work with me and offered the XXXX payment and XXXX other payments. I believe this is a scam cause I ca n't find that phone number listed to any law offices in the nation.
