I got a miss call from this number ...who is the owner of this #???

I let a call from this number go to message. "if you do initiate this verification someone may be trying to access your account Please press 0 pound to submit the final"  .
My Conclusion  - a   totally shonky call

I have received a call from this number and it seems to be a scam. The number appears to be from Microsoft.

Very suspìcious call. I did not answered. The recorded message was something like "Sistema de comprobacion de iniciio de sesion de Microsoft", and asked me to hit some keys.
Microsoft do NOT HAVE my phone number !!!!

Yes, this is Tech Support type scam. The crooks want to get access to your computer. Things got bad from there.

If this valid, why is it then that after this number caleed, the system was hacked, Is Microsoft employees then responsible?

Several call from this number saying internet not work but it was find?

Called me during midnight
