> I got a lot of calls here in Germany from people with indian accent, pretending to work for Microsoft. At some point I wouldn’t pick up the phone if I did not know the caller.
The person is clearly not talking about robocalls, but a spam/scam caller.
Not to say that those are the same but they often go hand in hand. The purpose of a robocall is typically just to cast the line, and if they get a bite then a human scam caller will take over.
