They called without leaving a message several times each day for weeks.
Today they called ten times.
I called back the number; a woman answered and said the calls were about selling insurance.
I said I did not want to do business with them, and asked to be taken off their call list.
She made a derogatory comment and hung up.

This company calls me several times a day trying to sell me life insurance. I have told them numerous times that I wasn't interested and stop calling me. They called me twice already today. I consider this harassment.
