frequent calls no one on the end of the line... stop call this number... freak.

Frequent calls morning and night.  I picked up and waited for someone to respond.  It is a "courtesy call" from some card protection company.  I told them, not politely, that I was not interested and to remove my number from their database.  I could not make out the name of the company as the lady had a strong accent and I had to ask her to repeat the name several times.  I will now block the number and report it.
