Who called from 2162820756

They keep calling won't leave a message and when you answer they hang up.

It's some kind of scam. I called back and they wanted my social security number. Said it was a business call.  I hung up on them.

Is thus s business number

I keep getting this number

This number calls me every morning around 9:30am. Doesn't leave a voicemail, but if I answer, they hang up on me. I have added to my blocked list.
