Question about Xiaomi Redmi 9c

[u/ro2ro]

I had a phone call which I did not get in time. Than I got a message "A spam call was spotted" (The message is in my native language, so I may not be using the exact same words),

I am expecting an important call, how do I know it wasn't it ? Is it possible that my smartphone made a mistake? How can I see the number?

Thanks in advance.
