Who called from 9784290903

I have received the call from the number 978-429-0903, there is no message ever. the caller id says it is from acton. I actually called it back the first time I saw the number because I know of people and businesses in acton. i had no luck in reaching anyone..always the same thing..busy signal, busy signal, busy signal..

Keeps calling no message

Caller ID said Acton, MA. I didn't recognize the number and didn't pick up. There was no message.

we make sure we are on do not call lists and yet this number keeps calling - I do not answer- caller id is ' not in use'.

Received call at 9:50 am, ID said Acton MA.  Usually don't answer unknown calls but answered this one.  Caller asked for my ex husband who hasn't lived here in 5 years.  When I said he wasn't here, could I take a message, I could tell that it immediately switched to a taped message.  For a non-existent breast cancer charity.  Hung up.
