Who called from 2102474614

Called,
no message

They called me and I answered and I answered. They asked for someone else but they didn't identify themselves.

I have repeatedly received calls from this number. It rings two or three times, no message. If I answer the call is dropped. This has been happening for a month now.

Same as previous post

It's 7:25pm on Wednesday 2-22-17. Home phone rang, I didn't answer (because I don't answer numbers I don't recognize). I let the call go to machine & no message was left, which tells me it's a scammer. If it's an important call (dr.'s office ect.) they will leave a message, that's the way I see it.
