I am also on the DO NOT CALL LIST, for both my home and cell phone. I get more than my share of calls such as this one, at least more than I should get while being on the list!
I am awaiting a way to find out how to get this type of harassment stopped! I do believe that I found a way to get a Diabetic Supply House cease! Thankfully my brother helped me make a good email to contact the FTC regarding that matter. The next time they called, I identified myself, told them that I was on the DO NOT CALL LIST. Should they again call, I would file a harassment suite! That was last Thursday (3/28/12) No calls since!!
