Who called from 7405249122

Several calls never leaves a message.

Got call from this number two days in a row.  Just says "unknown name" and no message left.

Unfortunately answered thinking it was a friend.  Person asked if I was (my name).  Without thinking answered yes instead of asking who was calling.  At this point the call disconnected.    Called the number back and it says it is ATT and press 1 to hear offers or 2 to be removed from calling list.  Pressed 1 and all you get is intermittent Muzak.  Contacted ATT corporate and they verified not them and will be researching.
