Telemarketing cold call claiming to be with US Healthcare (they also go by Medicare Specialists, Medicare Benefits, Insurance Enrollment Center). The telemarketers have heavy accents and their pitch goes on to say how they could save with Medicare insurance. I keep telling them there is no one here of Medicare age and that I am on the federal do not call list. I then said to remove my number and stop calling. At that point they typically respond with rude comments or just hang up, only to call again later on.
