Called reguarding Diabetic Supplies.

They call my phone 3 to 4 times a day.  When I call the number back they say push "2" to be removed from our call list.  For 4 weeks I have been pushing 2 and they still continue to call and the number is always 1 digit different from the last number they used.  They harass me at work and when I do speak to someone and inform them to not call me again, they just call from a different number.
