The numbers change constantly but are always with the 218 prefix . The next 3 didgets (264 this time.. indicating Grand Marais... a town near me) . I get several callers a day. They are trying to sell affordable Medicare coverage. When I tell them I have coverage A andB as well as additional insurance and I am also a disabled veteran .. they will not take no for an answer and they become combative and start reading their scripts LOUDER and faster! Just a nightmare ... I hang up on them but how on earth can I make this stop??!! I just got out of hospital with a diagnosis of stomach cancer and I am waiting for a referral to the Mayo Clinic so I have to answer all calls from mn in case it’s from a dr , Mayo Clinic or Case manager... I am very sick and on heavy medication... these calls are horrible. I hope I can live long enough and have time to bring this horrible public har**sment to the attention of our senators and congressmen/women and laws against this kind of privacy invasion can be stopped on the federal level!!
