We are retired people here, and go to bed early some times, so when the phone rings at 8:55P.M, we think for sure a family member is dead. I put our number on 3 nation wide (government) no call lists, and every other no call list there is.
We do have an answering machine, and I assume the hang-ups on there are from them. I tried the # sign & the 6-7-6-7,
and yesterday a (so called police) man asked for a donation, when I said we just gave at Christmas, he asked for more.
I believe we have to live with it. We do not donate to phone requests ever, as we like to pick our chairities.
