Beware, they also call from other fake numbers as well as private numbers. Best practise is if you don't recognise the calling number, or not expecting a call from a private number, don't answer. If genuine they will leave you a message, whereby you can verify them.

I called back number 0480 034 592 rang once then gets disconnected automatically.
