I'm not interested, please stop calling.

keeps calling to ask if i want to further my education....which i do not....they wont quit calling and this is my parents phone....make them quit

They kept calling me!!

I have been hanging up on the number several times a day for no less than 2 weeks now.
One of the times I answered earlier on (since it is my area code and could have been a doctors appt confirmation of something) and the gal said something about mentor and furthering my education. I said I was not interested and to not call again and they have done exactly the opposite as I stated above.
This morning when it started, I answered with "I told you yesterday to STOP harassing me!!!" to which she replied "May I speak to (my name here)?"  I repeated my statement and then went on to ask how many times were they going to call today and that they had called umpteen times yesterday. She replied "hmmm, yea, uh huh" as tho she knew it AND was proud of it!!  They have called once SINCE THEN!!!  WTH????
