Don't know 'em.

Multiple calls per day.  Leaves no message.

Calls many times.  I tried to call the number but got a message saying that "you have reached a non working number"

calls daily no reply when phone is answered

I received multiple calls from this number daily and sometimes after 9pm.  The 914 is my local area code so didn't use it when trying to call back.  A recorded message said 290-6339 was not a valid phone number and to try again.  I tried today calling with the area code and a recorded message said that it was the March of Dimes.
