Who called from 4048916821

may have been miscellaneous

Caller didn't respond when I answered, so I ended the call.

calls and after you say hello a couple of times, hangs up without speaking.

My Caller ID shows 404-891-6821 and "Contact Center."  Same behavior as others note, but once someone with an accent hard to understand came on and asked for someone who lives here.  Finally got through the accent and took a number to call back.  Then I threw the number away after talking with the person asked for.

Not answering that Caller ID any more.

Called 3 times, no one says anything
