I put myself on the 'do not call list' It has helped some but political calls come anyway. My husband was a good customer of 'Mid-American Tool". After his death they would continue to call. I informed them of his death and that I would not be ordering. Calls continued for 2-3 years. Finally quit - for about a yiear or more. Then another call!
I finally said "Dead people can't order" and hung up on them. Usually I am not dude but I had had it! No calls since.
