They called and would not say where they were from. It was a woman who said her name was Sheila, but was calling for my sister. When I asked where they were calling from, she wouldn't say. Then I called back using *67 and she answered again and didn't give a name of the company. I said I had the wrong number and she said no you don't, we just called you and I asked where she was calling from again and she wouldn't say. Very rude woman.
I had a similar experience. They called my house phone looking for my daughter who is away at college. Would not give me any information and was very rude. When I saw this posting it puzzled me. My daughter has no outstanding debts, medical or otherwise. All her medical bills go through our insurance.
