It’s a scam. Block that number if you can.
I get those calls about once a week. Sometimes they misidentify mu OS and the accent is usually Indic or Pak. I have a landline with no extras so I can’t block them but they are not much of an annoyance. They are operating out of phone banks and they are not on the phone when your phone rings. They switch to your phone when the one they are calling from lights up so it may be a couple of seconds before you hear a voice. If someone doesn’t say something in two seconds I hang up. I don’t run to the phone from across the house when it rings. It is only the most minimal distraction and these calls are another reason I won’t have a cell phone.
