Hello, can you hear me? Repeated again and again.
This is obviously a scam trying to get you to say the word "Yes" and "No" so they can record you and use it later, probably with telephone banking or similar to steal your money.

Didnt answer, Message bank bloke sounded english no message left. Not for me

Two different calls, probably some rich relatives died! As if

No reason for someone in Geneva to call me. Declined the call and they haven't called back.

I do not know anyone from Switzerland who would call my mobile. I simply hung up.

Fake call

Who do I know in Switzerland? Nobody. Has to be some sort of scam.
