Got a hangup call from this Chicago metro number a day after my dad's doctor insisted as a condition of treating my dad during his semi-annual visit that I give his office receptionist both my cellphone numbers. This one I showed her and specifically told her not to call it except in an emergency. I've been getting hangup calls and scam robocalls on both my cellphones since I refused to pay a medical bill of my own for substandard treatment and in which I learned my own medical records had been altered in the DC metro area. A major insurer/medical group and a major medical center in that metro area both insist that their medical status (and access to privileged people, i.e. movers & shakers) allows them to ignore federal and state laws, including the CANSPAM act (forbidding unsolicited calls to cellphones), FDCPA (debt collection activities) and HIPAA/HiTech Act (alteration of electronic medical records). The receptionist also wanted me to call their billing department concerning my dad's bills. I don't have them, but he thinks them pretty creative. Anyway, it seems the billing department doesn't actually have an address? Come on. How about playing by the rules, some day, some time, over the rainbow......
