Sign you mother up for the do not call list. Cuts the annoying calls by 80% and there is a benefit of reducing the chance that your mom get’s scammed.
I signed my elderly Uncle up for Do Not Call and Do Not Mail more than a year ago.
He still gets calls and mail ALL the time.
He’s gullible too and won’t listen to reason. He’s so broke now that he can’t afford his condo anymore.
Sad.
