Robo caller connected a live operator who actually sounded like they might be from the US - asking to speak with somebody not here and immediately hung up without waiting for a response. Brilliant. Given the name they used (they apparently have the creativity of a brick), it seems like they are probably part of a series of travel scam calls already received around here on an unpublished private number.
In those scams, they ask for a name, find out that they don't have the right number, but guess what? They're going to let you have the special travel deal that they had ready for just for him. Probably best to introduce them as quickly as possible to Mr. Click and Mr. Dialtone if you don't happen to already have a call number blocker.
