It's a Montana number.  I got a call this morning and heard a hello was all, a long silence then they hung up.

The same is happening to me. I get a few calls daily and when I try to call back, the number is disconnected. I wish I could block this number...Area code means it's from FL and I don't know anyone in FL!

If I find out who's calling me from this number ,they are f****ng dead

This is a scam number. They are using the affordable care act to target people!! DO NOT give them any information. They will claim to be calling you about your health insurance account. They will try to get you to give out personal information by asking you to verify it. Again Do Not give them any information...if the person they are calling for is not available they will ask you to call them back at this number.

I am getting several missed calls a day. When I go to answer it, no one is there. When I go to dial it back, just like Reba's comment, no longer in service. How can I get this number blocked?

Even tried to call back and number is no longer in service, changed.  How do we block the number?

I have been getting several missed calls daily from this number for the last week.  They always hang up when I answer.  Are you still getting calls from them?
