Who called from 2029719025

They've called a couple of times and left no message.  Caller ID just shows 'Washington DC.'  I actually picked up the receiver on the second call, but they hung up.

same as above.  multiple calls with no message.  when I did pickup they immediately hung up.

4 calls in 3 days. Never anyone there. When j return it, it goes to VM

I've been getting one or two calls a day from this number everyday for the last few days. I've never picked up because I don't answer calls from numbers I don't know. It's getting really annoying though and I am probably going to look into getting that number blocked.

I have received 6 calls from this number in 3 days , two every day and they never leave a message I have blocked them on my cell phone hopefully that will work.  Caller id only says DC, USA
