Who called from 2074945819

Phone call from 207-494-5819 caller ID Women's Cancer, woman asked if she was speaking to and used my first name.  I replied "yes"  went to dead air then disconnected.  I called the number back and it was a disconnected number.

Keeps calling. I said good morning and it disconnected. When I called back it was a disconnected number.

Has called a few days, answered, they hung up, called it back says number is disconnected.

had the phone number on my phone caller id  called it back... disconnected number   WTF

Caller addressed me very familiarly after I answered: used my first name, told me I was "hard to get hold of."  Started going into a spiel.  I told her we do not respond to phone solicitations.
