Prefix 0407 794

Caller Type: Unknown

automated voice said they were calling 2 confirm my purchase & delivery of an iPhone @ Amazon on your plastic card if this is correct just hang up if not press (1) which I did! Only 2 have the message repeat itself so I keep on pressing(1) until it went silent i could hear an Indian man faintly in the back round then they hung up! I received a similar call a few weeks ago thanking and confirming my Amazon prime yearly subscription but i was out and carrying shopping so wasn't able to address it @ the time I just put a hold on my card when I got home but now im worried about identity fraud!
