scam call for sure

I received a call but no message was left. I rang the number back but message said the number was not in service.

Asked for our boss by the name he very rarely uses, when I said that yes they'd called his company and what was up, they hung up without saying anything else.

Indian subcontinent accent, woman, very busy sounds in the back (like a call centre)

missed call to mobile. no message left

I didn't answer and then i called back and said the number was disconnected so definitely spam.
