Number 0407 785 620 called and left no message. Within 10 mins a call from a further number 0407 727 524 same thing no message. And again another number shortly after 0407 759 688 Then again 0407 782 923 And finally 0407 757 289 Am I right to question that I'd have five calls from unknown numbers, with no message left, within 1hr 10mins?
