Are the above sentences correct? Please advise and thank you for your help.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
Note that although you will hear it, "I received a missed call" doesn't really make sense. If you missed the call, then you didn't receive it.
I missed a call ...
I got a phone/mobile message/notification of a missed call ...
