@literary Super!
@indigo Yes; I could do that. But I think, most of these calls come from contact/call centres; right? At least that's way it is.
Some one from my bank called to tell me that there's a new mobile app that I could use for online banking and it works with fingerprint log-in. I asked him, how do I know for sure that he's actually calling from the bank? He was unable to provide me with a good verification method.
I think, it's time to pack up for the day. One meeting and but otherwise rest of the day managed got along with my own stuff.
