Repeated and constant calls from this number for the last few years - Caller ID shows "LLS Donations".  They claim to be a leukemia society but, when asked directly, refuse to divulge any information about their organization.  We have asked them repeatedly to have our number taken off their call list (our number is on the National Do-Not-Call List).  Representatives are extremely rude when asked to stop calling, or they hang up.  

For several months, we would answer their calls then immediately disconnect, however, this group calls a minimum of two times per night, sometimes as much as 3 times per week.  Recently, we have started blowing an extremely loud police whistle into the receiver when this organization calls.  This seems to work, although briefly.  We have received two calls from "LLS Donations" in the last three months, and each time we have answered the phone with a piercing whistle-blast.
