Telemarketer peddling diabetes supplies. I made up a tall tale telling him I don't pay for my supplies, I steal them. That didn't put him off he continued his telemarketing prattle. Finally I just hung up.
You can go to www.donotcall.gov. Register your phone number and then when any of these types of calls come in, register a complaint. Apparently, if the company if found to be violating cold calling procedures, you will receive a portion of the the fine that will be imposed against them.
