Who called from 4029881014

Called, but no one on the line

Another of those no-one-there calls, probably an overworked telescammer.

They left no voicemail.  When I called back, the pre-recorded greeting said, "Your call is very important to us.  You'll be helped by the next available agent".   About 5 seconds later, I heard someone pick up and heard a call center in the background then they immediately hung up.
