CAlled but didn't leave a message and continues to call approximately every 2 hours on every day of the week.

Got this call twice today. Missed the call. Caller ID said CMO-MMC. Is this telemarketing?

According to our Google search, this appears to be the fax line of a Stop and Shop fax line in the Bronx (NYC). We've been called at eight at night and again at 12:30 in the afternoon (Eastern time).

I got a call from this number.  No msg was left for me.  When I tried calling back, I keep getting a busy signal.

Received a doctor's appointment confirmation for a patient <patient name withheld for the person's privacy> of Dr Zalte at Montefiore Medical Center. No idea who either party is and can't seem to reach a human at Montefiore who can help.
