Who called from 8023705450

I answer but the line goes dead.  Called back and Automated system says number does not exist. I have gotten three calls today from this number

I get calls from this number, they hang up if I answer it.  I found out it is a cell phone in  St. Albans, VT  on Sprint, Franklin-County, 05479-zip

I have gotten the calls from this number as well. It is interesting that we are all getting them on the same day. I had been receiving phone calls from an unknown number a few days ago..anyone else experience this?

I get the same thing as the other comment they call then hang up. You call them back and it sya not a working number!!

Same here. Same day (yesterday)
