don't call again

Calls continue - two just today. They're now calling themselves "an American financial institution" (notice the "an") which is the third name they've given, the others being "American Financial" and "United Services." Now they claim to KNOW that you have debt (as if they'd done research and had seen your financial records), but then proceed to ask you what debt you have. Requests to stop calling have obviously gone unfulfilled.

Keep calling me. Getting sick & tired...

Got two calls, hangs up on answering machine, tried to call back but number is disconnected?????

The above number continues to leave threatening messages on my voice mail. Such as, if you listen 3 seconds longer, we will assume you agree that you owe this debt. But you have to listen to the entire message to make any sense out of it. It is a collection agengy, I believe she left a name of Cathy Martins, but she mumbles over her name so you cannot quite tell. She is looking for someone who has never lived in our home. She is calling 3 to 4 times a day. How can we get her to stop?
