Who called from 4043714561

Getting weird calls from this number

I just got a phone call from this number 404-371-4561 and he asked for me by my full name. I couldnt understand his name or where he was calling from. When I asked him to repeat what he said he got frustrated and said he knows I have a VA loan and wanted to know the interest rate I was paying. I told him that the've called me before and I told them I am not interested in refinancing my home and he rudly hung up on me mid sentance.

This number called twice and no one says anything. Third time someone said something couldn't understand. It was too my cell number. Obviously spam. I blocked the call

I never pick up the line, but this number along with others from across the country do the same thing.  when you ring back, it's disconnected.  

getting a call daily from this number. I do not know who it is and they never leave a message for me to call back. I blocked it.
