Hang up call from 313-209-4197. Caller ID shows only "Detroit, MI". Based on previous comments and other research on other sites, this number 313-209-4197 belongs to a telemarketer. The number they called me at has been on the National Do Not Call Registry (donotcall dot gov) for two years, so they are in violation of federal law.
Called husband's phone a few minutes ago. Didn't answer, they left no message. Adding the number to a contact labeled Bogus, and set it to no ringtone. Now when they call back the phone won't ring and we won't be bothered.
