Very rude.  scam.

Thick Indian accent, call center background noise, and this time his name is Alex Greenburg from the National Medical Center.  Asking for an employee saying he needs to confirm her dental appointment.  he hung up on me, called back and when i said, "you just called and hung up on me" he said the call was disconnected.  i put him on hold and he hung up. This gatekeeper is having the number blocked!!  You don't to scam my people today!!

called asking for an employee who no longer works here, when I said I didn't have number in my system, he started getting angry and saying I lied to him. Then he hung up in the middle of a sentence.

Keep receiving this call asking for patients from the University of Pennsylvania. We are a MN based company.

Received a call asking my name, I said yes. Then he hung up. Called me at work.
