this number keeps calling everday more than once, my mother is 88 so they keep telling her that they are a diabetic supplier, well I take care of that for her, so I told them to quite calling and I wouldn't let the women get a word in so she got mad and called me a fking [***], so I slamed down the phone and she called back and my brother answered this time and she wouldn't say anything, but she still is calling my mother. so what can a ;person do
