i called this number and a male answered the phone - appeared genuine that he did not call my number and stated he has not called anyone for a last few days.

It reminded me...
only few days ago, i was waiting for a phone doctor consultation and answered a call immediately, thinking it was from the doctor (i normally do not answer if not known), a male told me he got a missed call from my phone number.

I actually did not call anyone or his mobile number in the last few days, EXCEPT I called medical centre which was a desk phone number (not mobile number)

I wonder whether the scam idiots now using another method - if unanswered, the miss called number displayed somone else's mobile number (random)

I HATE those scam idiots - dont they have anything better to do, constructive instead of destructive.
