User reviews for 720-640-0721
Heavy breathing and stayed on the line for 20 seconds. Won’t respond to “hello” or “who is this?” Might be a caller recording voices for impersonation.
This number 7206400721 called me yesterday and early this morning. I thought it was something important. I'm returning this call now but there is no answer. I'm trying again and now it seems I'm losing the connection. Pretty strange. I think I will ignore this number.
